Defective roll of foodsaver bags?

Recommended Posts

It is only one month since I acquired a Sous Vide Professional, and during this time I have been experimenting here and there. This includes cooking meat for 3 days (twice) and 2 days (once), and several experiments with vegetables and pears (cooking at around 90 C).

I have finished 3 rolls of bags without any problem, and milk at 90.5 C.

But yesterday I started a new one. The new roll (8", Foodsaver) has resulted in two bag failures out of 2 bags.

The failures have been in the sides of the bags, not in the seams I make (I usually seal them twice to make sure they will not leak).

The first case was 1 l. of milk at 90.5 for 40 minutes. As I was extracting the bag the seams gave up IN BOTH SIDES at the same

height.

Second time was 1 leg of duck at 82 degrees (after around 7 hrs). It opened in one side, as it was cooking (the smell of duck gave it away, fortunately it wasn't too much of a mess).

Has anybody else experience something like this? I might start double sealing the seams just to make sure...

The short answer is that, yes, you should double-seal the bags.

Any time you have any liquid in the bag whatsoever, there is a chance some of it might get into the sealing area and make the seal less secure -- perhaps not immediately, but over time. One technique to counteract this is to seal the bag once leaving a fair bit of extra bag after the seal, then wipe out the extra bag well with a paper towel and seal the bag again in that area. The seals themselves should be clear, with no folds or anything like that.

Also... FoodSaver brand vacuum bags suck. Do yourself a favor and get some 50-foot rolls of bagging material from these guys. I think a FoodSaver should be able to use the 8" and 11" widths, but not the 15" width.

Yes, it has happened to me but only on one occasion and it was the side-seam that failed not the seals I made. However, it was not a FoodSaver brand bag but one I bought in bulk from a restaurant supply store - there are no brand names on these bags. One could double seal the side seams but only on bags that don't exceed the length of seal bar on your machine and that is a pain!

That definitely sounds like a defective roll. I ran a through quite a number of FS rolls and never had a single failure from a side seam..

      I've had the CSO for a number of years now, but have yet to actually bake bread in it.
       
      Reading through the Modernist Bread thread on this forum I see many of you are using the CSO to great effect, which is heartening.
       
      To that end, I would like to know about your experience baking bread in it – what sort of extra equipment you use (pans, cast iron? etc), what breads work the best, any corrections you find yourself making, or anything you feel might be useful to someone else using the CSO.
       
      Thank you!

      The space race trickled into kitchens in the 60s and 70s, including one curious tool that's faded away in the years since: the thermal pin, a heat pipe skewer that can halve cooking times for roasts:

       
      Heat pipes are thermal superconductors, transferring heat 500-1000 times more effectively than solid copper (some people in the sous vide thread have discussed copper pins). They're hollow tubes with the air evacuated and a small amount of working fluid, often water. The usable temperature range is limited by the triple point and the critical point, with additional constraints near the edges. Water is effective from 20C-280C /70F-530F, which comfortably spans most cooking temperatures.
       
      Modernist Bread has an excellent section on how bread bakes, including a diagram of the internal heat pipes that develop, summarized here. (click for a good photo!)
       
      Sous-vide solves the overcooking side of the gradient problem, but it's still limited by total heat diffusion time-- doubling the size of a cut quadruples the time needed for the center to reach temperature. Heat pipe pins should make larger cuts practical, or normal cuts cook faster. Here's a graph from "The heat pipe and its potential for enhancing the cooking and cooling of meat joints", showing average temperatures over time for 1kg joints of meat convection baked at 190C/375F for 110 minutes (foil removed for the last 30 minutes):

       
      Thermal pins were sold commercially from 1956 to about 1990. They're listed occasionally for about $20 on ebay. They even made potato baking racks with heat pipes-- though now you can easily par-cook a potato in the microwave and finish it in the oven.
       
      I don't know why production of thermal pins stopped, or what fundamental problems limited their usage. It seems like pans and commercial griddles would be improved by adding heat pipes to spread heat throughout and avoid hot or cold spots. Perhaps roasts fell out of favor as the culture of entertaining shifted away from monolithic centerpieces to smaller, more precisely cooked portions.

      Hey there, i hope to find some help in the wise hands of yours. after some research i am still having some problems concerning glazing:
       
      For a party i would like to make some cubes and rounded savoury cakes and foams out of silicone forms that have a ready bottom and a colour glazing. 
      Somehow i just do not manage to find a steady glazing ( one that does not run ) and is for texture reasons preferably hard or crisp that does not include sugar or syrup.
       
      can you help me or lead my way in a certain direction?
       
      thanks very much!

      Is there a discussion in the book about the purpose of adding ascorbic acid?  I just saw the contest #2 in which the recipe called for it.  I'm curious because a woman I know on the internet used to work in a bakery in Vietnam, and said that to get similar results to the banh mi there, you need to add ascorbic acid.  Does it act as a gluten relaxer?  Traditional banh mi have a very tender and crisp crust, and a very light and tender, relatively closed crumb.

      Having experienced the "Edible Balloon" dessert at Alinea, I have been on a quest to try this at home.  Only recently was I able to find purportedly a recipe:
      https://www.buzzfeed.com/raypajar1/these-edible-helium-balloons-are-dessert-from-the-future?utm_term=.ut6r3PnMk#.acGNVWmd6 the video of which is found below.
       
      I tried this and probably no surprise, it failed.  The bubble collapsed / popped with only a little distension.   I wasn't sure if the problem was that a "secret" ingredient (e.g. some kind of surfactant to stabilise the bubble or using a different kind of sugar) was missing.  Or maybe I didn't allow the mix to come to correct temperature etc.  Elsewhere I thought I had read that the original recipe was in effect some kind of taffy.  Has anyone else had success, or do any candy makers /modernist chefs, have suggestions they are willing to share?
