Does anyone know anything about this? It looks like an interesting app but the Apple store does not seem to have any info on who created it. Neither are there any reviews. I'm a new sous vide user who needs all the help she can get and am wondering if this app would be helpful.

Thank you!

Thank you!

I created it for my own use, and recently released it in the app store. Needless to say I'm a little biased, but the app works well for me.

It looks like there are not enough Canadian ratings for Apple to publish them yet, but you can see the US ratings and reviews at http://itunes.apple.com/us/app/sousvide-dash/id476999798?mt=8. As of this writing, the current version (2.0) has three five star reviews and five five star ratings and nothing at all giving it four stars or less. I'm quite proud of that feedback, but still working on adding features and improvements for upcoming releases.

You can get more details and see a video quick start guide at www.sousvidedash.com.

Vengroff, I just purchased the app. It looks like it will be really useful. I have also watched the videos. I do have one question - can I change it from Celsius to farhenite and mm to inches? I'm in Canada which does use the metric system but being a person " of a certain age" I am more comfortable with farhenite and inches. No big deal, as I can use metric, but I'm just wondering................

Thanks, Elsie.

Yes, you can change the units. Quit the app entirely, then go to settings on the home screen (the gear icon). There is a section for app settings. Scroll down to SousVide Dash and you will find options for C/F and mm/in. Choose the units you want, then restart SousVide Dash. If SousVide Dash is in the background when you change settings, instead of completely closed, then you may not see the change take effect immediately. Change the food settings to force it and you should be good.

A new version of the app just hit the US app store. It should be available around the world within 24 hours. From the release notes:

This version (2.1) of SousVide Dash is the first that runs on iOS 5 only. Transitioning to iOS 5 enables us to take advantage of some unique new features in upcoming versions of the app. It also increases the reliability of our testing processes.

Most of the users we surveyed told us they are now on iOS 5. We decided to do this transitional release to give the rest of you some time to upgrade.

New features include:

- More equipment supported.

- Twitter integration. Tweet what you are cooking to your followers.

There will be some big additions in the next release, such as support for computing ice bath cooling times, so please take this opportunity to upgrade to iOS 5 so you are ready for the next release.

I'm really excited about the new version 3.0 look that we are testing now.

As shown below, there are three big changes:

1. An option to add additional cooking time for tenderness. This is tacked on after the food reaches temperature.

2. An option to cool the food in an ice bath after cooking. This is enabled, and you can see the effect in the graph where the temperature drops when it hits the ice bath.

3. A new display with a summary of key events followed by a detailed time line of every potentially interesting event in the cooking process. This is scrollable so you can see everything that is going to happen. Pathogen details are at the bottom below it (not shown here).

It's going to be a few more weeks before this hits the app store, but I wanted to see if there is any early feedback. I really like this new layout, and am eager to hear if you do as well.

It's looking great! Now all it needs is the ability to save/print/email the "recipe" so you can remember what you did!

Can you say 3.1?

As a newcomer to sous vide cooking, I am still on a steep learning curve. However, this app has really helped me. I don't know if this is feasible but in addition to starting food from frozen, it would be nice to know how long to re-heat food. For example, I have beef braising ribs which have been cooked sous vide in the freezer and I have no clue as to how to go about re-heating them. I had cooked sous vide pork chops back when I first got my immersion circulator and then had to guess at how long to put them back into a water bath from a fridge temp to re-heat. The chops were not as good as when I seared them immediately after removing from the hot water bath. Like I said, this might not be feasible and maybe there already are instructions for this somewhere and I haven't found them yet.

In general, it just needs to be in the bath long enough to come to core (serving) temperature, that is assuming it was first cooked sous vide to the desired degreee of doneness and for whatever pasteurization you wanted, then quick chilled without opening. If you had opened the pouch then resealed, you may want to re-pasteurize as well.

It would be nice to have the option to start the food temperature at freezer temps in addition to refrigerator temps.

We are exploring this. The simulation gets a little challenging, so it's going to take some work. I have spoken with Douglas Baldwin and other experts and I now understand the problems, but don't have an accurate solution yet.

The basic problem is that while the food is defrosting in the circulator there are three distinct zones each of which has its own unique physics. The outer zone is fully defrosted and starting to cook like food out of the refrigerator. The middle zone contains a slushy mixture of water and small ice crystals. The innermost zone is still fully frozen. Over time the inner and middle zones shrink and eventually disappear. But keeping track of how the boundaries between these zones move over time adds complexity to the model. In time I'm sure we will figure it all out, but it's going to take a while and we'll need some very extensive testing to validate the models.

Thank you. You should be able to calculate reheating times using the time-to-temperature mode. This will compute how long it will take the reheat from refrigerator temperature to your desired serving temperature. Just make sure you cooked to pasteurize to the core the first time and cooled in an ice bath before you put the sealed bag into the refrigerator.

So in the case of my braising ribs, they were cooked sous vide for 48 hours at 133F, quickly chilled in an ice bath and then frozen in their vacuum packs. I guess then I would thaw the meat in the fridge, set the water bath to 133F and, using the sous vide app calculate the time to reheat? In this instance, the meat is 11/2 inches thick and the stuff that comes out of my fridge is 34F so that would take 2 hours, 47 minutes and 48 seconds. Reheating the meat this way will not alter the texture but simply bring it back to just-out-of-the-water bath consistency that it was at when I initially cooked it? Am I understanding this correctly? If I am, that sure fills quite a big gap in my knowledge of things sous vide.

      Introduction

      Welcome to the index for the Sous Vide: Recipes, Techniques, & Equipment topic, one of the largest and most influential topics on eG Forums. (The topic has been closed to keep the index stable and reliable; you can find another general SV discussion topic here.) This index is intended to help you navigate the thousands of posts and discussions to make this rich resource more useful and accessible.

      In order to understand sous vide cooking, it's best to clear up some misconceptions and explain some basics. Sous vide cooking involves vacuum-sealing food in a plastic bag and cooking it in a water bath at precise temperatures. Though it translates literally as "under vacuum," "Sous vide" is often taken to mean "under pressure," which is a misnomer; not all SV cooking involves food cooked in conditions that exceed atmospheric pressure. (See below.) In addition, calculations for SV cooking involve not only time and temperature but also thickness. Finally, due to the anaerobic conditions inside the bag and the low temperatures used, food safety issues are paramount.

      You can read the basics of SV cooking and equipment here. In the summer of 2005, Nathan Myhrvold (Society member nathanm) posted this informative, "I'm now going to answer my own initial questions" post, which addresses just about everything up to that point. For what came next, read on -- and be sure to order Nathan Myhrvold's highly anticipated Modernist Cuisine book, due in spring 2011.

      As with all indexes of on-going discussions, this one has limitations. We've done our best to create a user-friendly taxonomy emphasizing the categories that have come up repeatedly. In addition, the science, technology, and recipes changed over time, and opinions varied greatly, so be sure to read updated information whenever possible.

      Therefore, we strongly encourage you to keep these issues in mind when reading the topic, and particularly when considering controversial topics related to food safety, doneness, delta T cooking, and so on. Don't read a first post's definitive claim without reading down the topic, where you'll likely find discussion, if not heated debate or refutation, of that claim. Links go to the first post in a series that may be discontinuous, so be sure to scan a bit more to get the full discussion.

      Recipes were chosen based solely on having a clear set of information, not on merit. Indeed, we've included several stated failures for reference. Where possible, recipes include temperature and time in the link label -- but remember that thickness is also a crucial variable in many SV preparations. (See below for more information on thickness.)

      History, Philosophy & Value of SV/LTLT Cooking

      Over the years, we've talked quite a bit about SV as a concept, starting with this discussion about how SV cooking got started. There have also been several people who asked, Why bother with SV in the first place? (See also this discussion.) What with all the electronics and plastic bags, we asked: Does SV food lack passion? Finally, there have been several discussions about the value of SV cooking in other eG Forums topics, such as the future of SV cooking, No More Sous Vide -- PLEASE!, is SV "real cooking," and what's the appeal of SV?

      Those who embrace SV initially seek ideas about the best applications for their new equipment. Discussions have focused on what a first SV meal should be -- see also this discussion -- and on the items for which SV/LTLT cooking is best suited. There's much more along those lines here, here, and here.

      Vacuums and Pressure in Sous Vide Cooking

      As mentioned above, there has been great confusion about vacuums, pressure, and their role SV cooking. Here is a selection of discussion points on the subject, arranged chronologically; please note that later posts in a given discussion may refute earlier ones:

      Do you need a vacuum for SV cooking, and, if so, why? What exactly is a "vacuum"? Click here, here, and ff. Are items in vacuum-sealed bags "under pressure"? Does a vacuum sealer create a vacuum inside the bag? Do you really need a vacuum, or can you use ZipLoc bags? Also see here, here, and here. If "sous vide" means "under pressure," aren't the items in the bag under pressure? There is more along these lines to be found in this discussion.  

      The Charts

      We've collected the most important of many charts in the SV topic here. Standing above the rest are Nathan Myhrvold's charts for cooking time versus thickness and desired core temperature. We worked with him to create these three reformatted protein tables, for beef, fish, and chicken & pork.

      Nathan provides additional information on his charts here. Information on how to read these charts can be found in this post. For an explanation of "rest time" in Nathan's tables, click here.

      Other Society members helped out as well. Douglas Baldwin references his heating time table for different geometric factors (slab/cylinder/sphere) here; the pdf itself can be found here. pounce created a post with all three tables as neatly formatted images. derekslager created two monospace font charts of Nathan's meat table and his fish table.

      Camano Chef created a cumulative chart with information gathered from other sources including Thomas Keller's Ad Hoc. Douglas Baldwin shared this chart devoted to pasteurizing poultry. PedroG detailed heat loss and steady state energy consumption of sous vide cookers in these charts.

      Finally, there is also an eG Forums topic on cooling rates that may be of interest.

      Wikipedia defines pork wings as: a pork product made from the fibula of a pig's shank - a single bone surrounded by lean, tender meat.
      Images from the internet look like a finger-size bit of meat around a bone.
      Mine, however, look more like the meat (lots) which surrounds a bone. My butcher called this cut pork wings.
      You can see on the right that there's a small amount of bone.
         
       
      My butcher said he regularly ate SEVERAL of these. But this one measures 15 oz (425g).
      He also said it had to be cooked slowly.
       
      So, if I cook these sous vide, what temp and for how long?

      Good morning!
       
      Long story short: I am doing a spin off the coconut/chocolate/almond candy (almond joy), and trying to create a specific shape out of the almond.  My hands are cramped after a couple dozen failed attempts whittling roasted almonds, so now I'd like to try a different approach, and instead, create some kind of sub-candy or cookie with roasted almonds that I can put into a mold or use a mini cookie cutter.  I'm fairly new to sweets, my knowledge in this area is pretty slim.  Some ideas so far, I don't like any, but it might help turn some gears:
      1. dusting almond over a stencil, but that's not enough almond nor crunchy enough
      2. almond brittle, but that's too hard and sweet, I'd like it more of a soft crunch, and bringing the almond flavor forward
      3. meringue with almonds (sort of macaron-ish), however, weather has been humid and raining here, and I'm ending up with a gooey mess instead of that soft crunch
       
      In addition to having almond-forward taste and soft crunch texture, it'd be fun to explore something modernish - I have a accumulated a few tools and ingredients not customarily found in homes.
       
      There are dietary considerations I will have to account for, however, no need to worry about that now, I am just looking for ideas and a place to take it from there
       
      Thank you for your time in reading!

      FOOD BRETHREN!
      I need some advice. I have one last piece of pork belly confit in the fridge. I brined these bitches for about 5 days (brine included pink curing salt), vacuum sealed the squares of pork belly with lard and sous vide them at 158 F for 16 hours. I cooked this on 11/10/16 and its been in my refrigerator since. 
      Here is the general recipe I followed, with some modifications based on my taste: https://www.chefsteps.com/activities/...
      The last piece is still vacuum sealed and submerged (mostly) in lard. Any visible pork only has contact with the bag. 
      It's staring at me. And calling my name.
      I want to deep fry this sucker and have a little date night with the handsome devil I see in the mirror every morning, but the last thing I want is spoiled food. I can't find any conclusive information about how long pork confit lasts for. I've only seen references that duck confit or in general that the confit technique will last for months in the fridge. I have found no sources which directly addresses pork confit.
      Questions/Factors I'm Considering:
      - Does pork confit keep for as long as duck confit?
      - Does vacuum sealing have any effect on the length of preservation?
      - Does sous-vide cooking method affect the length of preservation?
      I know I am probably being a bit paranoid, but I thought I would do my due diligence before taking the plunge, so to speak. Any advice on these questions would be extremely helpful and appreciated!
      The Franzisaurus-Rex
      PS - you should totally make this if you are into sous vide, confit, food, or have any respect for the enjoyment of life. Flash-searing these things after cooking was OUT OF THIS WORLD.

      The NY Times has a current article in the science section "A Universe of Bubbles in Every Champagne Bottle".
       
      The article asserts that it is better to serve Champagne at warmer than refrigerator temperatures so that the bubbles are larger and convey more flavor.  Also to serve in a narrow glass.
       
      However Gerard Liger-Belair (who is referenced as an authority in the Times article) points out in his book Uncorked (forward by Herve This) that the colder the wine the more viscous and the more dissolved CO2.  Liger-Belair also prefers a goblet to a flute.  I bought Uncorked after reading about it in Liquid Intelligence from Dave Arnold.
