In addition to tonic water (which contains quinine) you can also use riboflavin (vitamin B2) which will glow with a bright green/yellow color under a black-light.

Great title - great topic! I live in Europe, love to cook - also from American cook books, but in the end I got tired of using single ingredient conversion websites, so I put together a Excel calculator which converts about 275 ingredients from US customary volume measurements to grams based on densities (corresponding to the Estimation method mentioned above). It recognizes all the common volumentric measures such as t, T, floz, c, pt, qt and gal as well as the weight measurements oz and lb. The calculator includes a differentiated rounding algorithm, so that you do not end up with recipes that call for 943 grams, but rather 950 grams (but always taking care that the imparted error stays low, typically below 2-3%). It's still a work in progress, but many have found it useful already. Densities are mainly taken from rec.food.cooking’s FAQ and conversion file (this is the same source as "Convert me" is built upon) and USDA National Nutrient Database. The most tricky ingredient by far is flour, so I added "spooned" and "scooped" as choices for all-purpose wheat flour. The excel calculator is available for free download from: http://blog.khymos.org/2014/01/23/volume-to-weight-calculator-for-the-kitchen/

OK not an app, but close enough: I got tired of using single ingredient conversion websites, so I put together a Excel calculator which converts about 275 ingredients from US customary volume measurements to grams based on densities. It includes a differentiated rounding algorithm, so that you do not end up with recipes that call for 943 grams, but rather 950 grams (i.e. always taking care that the imparted error stays low, typicall below 2-3%).

Thanks - I'm glad you find it useful! When using Texture - consider taking a picture if you follow recipes without a picture. That way you can all help make Texture even better.

Thought I'd let you know that a major revision of Texture is now available for download: http://blog.khymos.org/2014/02/15/texture-updated-and-available-for-download/ "Texture - A hydrocolloid recipe collection" (v.3.0) features: many new recipes, now counting 339 in totalmore pictures (A big THANK YOU to all contributing photographers!)a new chapter with non-hydrocolloid gelsa new table with viscosities of 1% solutions of hydrocolloidsmany minor corrections throughout the recipes and appendixconversion from US customary volumetric units in new added recipes done with Excel calculator available from http://blog.khymos.org/2014/01/23/volume-to-weight-calculator-for-the-kitchen/

Chris Young found time in his increadibly busy schedule to reply to my interview-by-email a couple of weeks ago. Amongst other things he explained a little about how he became part of the project and his time at The Fat Duck. He also shared the email from Nathan Myhrvold that got him on the team: > From: Nathan Myhrvold > Date: Sat, 21 Jul 2007 > To: chris@thefatduck.co.uk > Subject: Crazy Idea > > Why don’t you come work for me? > > Nathan BTW Chris Young presented Modernist Cuisine at The Flemish Primitives in Oostende, Belgium on Monday. I was so lucky to peak into what was possibly the first copy ever in Europe

Version 2.3 of the recipe collection is now available for download. The major change since version 2.3 is the inclusion of pictures. The pictures often give you an idea of the texture, and they're also a good indication that the recipe has indeed been tested. There are now approximately 310 recipes in total now. And one more thing: You can still help me add more pictures to the recipe collection! You can find more information on how to contribute pictures in my post from January 5th.

Back in 2007 Jack (jackal10) came up with a wish for pictures in his reply to one of my first posts. Already then I thought that it would be great to expand the collection with pictures. And finally I've now started the work to collect pictures - sorry it took so long. But to get things going I definitely need all the help I can get. Here's the deal: A picture is worth a thousand words, and this is also true for recipes. Several who have downloaded “Texture – A hydrocolloid recipe collection” have asked for pictures and now it’s time to do something about that! A picture can illustrate texture well and is an excellent supplement to the descriptions. I therefore invite to you to contribute to the recipe collection by taking pictures to accompany the recipes. But before you run to grab your camera, please take a note of the following: Pictures should clearly show the component described in the recipe. If you take a close up picture against a neutral background it’s good if one still has a feeling of what the scale is. Only send a picture if you actually followed the recipe! This way the picture can also serve as an indication that the recipe as been tested. However, if you for some reason have modified a recipe for a better or different result I would also be very interested in hearing about this. Pictures should be in focus and well lit. But remember that Photoshop can do wonders, so please do send pictures even though the colors seem a little dull. Pictures will be cropped to a 1:1 aspect ratio as shown above Preferred minimum resolution is 450 x 450 pixels It’s a requirement that the picture is taken by you and that you are willing to provide it for use in “Texture – A hydrocolloid recipe collection” under a Creative Commons Attribution – Noncommercial-Share Alike 3.0 Unported License since the whole recipe collection is published under such a license I reserve the right to crop pictures and do color/brightness/sharpness adjustments I reserve the right not to use pictures received (and I only intend to include one picture for every recipe) Pictures will be attributed to the photographer as shown in the above illustration. If you have read the above and agree you’re ready to send your texture pictures to me at this email address: texture.pictures (at) gmail.com. Remember to include the name of the recipe photographed and your name as it should appear under the picture. Thank you very much for helping me make this collection even more useful!

Just a small note to let you know that I've just published an update of "Texture - A hydrocolloid recipe collection" (version 2.2). There are two file sizes available: screen resolution (~1 MB) and high resolution for printing (~5 MB). It published under a Creative Commons Attribution-Noncommercial-Share Alike 3.0 License so the download is free. What is new? The total number of recipes is now around 270. Supplier list updated New index for alcoholic preparations Small glossary added Typos corrected As usual I'm always interested in feedback. You are always welcome to provide new recipes. What can be done to further improve the collection?

The smaller diameter of the glass cylinder will make layering easier (compared to layering in a soup bowl for instance). A slight increase of viscosity will prevent mixing of the layers. The glueing part is tricky as you want something which tolerates water (at least for a couple of minutes), yet it shouldn't stick to hard to the plate (or the soup would end up everywhere else than in the bowl when guests need to use force to release the soup. I agree that gelatin might work, but probably only with cold soups. Remember that gelatin melts around 40 °C. Your options then are to use agar (80-90 °C), low acyl gellan (does not melt), high acyl gellan (70-80 °C) or high methoxyl pectin (does not melt). For all the hydrocolloids you'd probably need to use higher concentrations than for normal gelling. Caramellized sugar could also work as it doesn't dissolve that fast.

Just to let you know that version 2.1 of "Texture - A hydrocolloid recipe collection" is now available for download. Changes include corrections of typos, minor additions to the property tables plus an important update in the gelatin section and a recipe for agar filtration (similar to gelation filtration, just faster!). There is also a formula for conversion between gelatin bloom strengths. More info on the formula for conversion between gelation of different bloom strength: Note that this formula differs from one found in another egullet thread - the simplest way to compare the two formulas is to multiply the bloom strength with the weight or the check the formula is to multiply the bloom strength of a sheet with the weight of the sheet. I got better results by omitting the square root, i.e. simply assuming that the product of the weight and bloom strength is constant. Avg bloom g/sheet bloom * weight sqrt(bloom) * weight 140 3.3 462 39 170 2.5 425 33 205 2.0 410 29 250 1.7 425 27 Relative standard deviation for product using "new" formula: 4% Relative standard devation for product using "old" formula: 17% New formula: mass B = mass A x (bloom A/bloom B) Old formula: mass B = mass A x (bloom A/bloom B)^0.5

Texture - A hydrocolloid recipe collection It’s a pleasure for me to announce that an updated version of the hydrocolloid recipe collection is available for free download as a pdf file (73 pages, 1.8 Mb). What’s new? Several new recipes have been added (now counting more than 220 in total), including recipes with cornstarch, guar gum, gum arabic, konjac and locust bean gum. All in all 14 different hydrocolloids are included (plus lecithin which technically isn’t a hydrocolloid). In each section recipes are now sorted according to the amount of hydrocolloid used. The appendix has been updated with tables for comparison of hydrocolloid properties, hydrocolloid densities and synergies. The perhaps biggest change is that all recipes have been indexed according both to the texture/appearance of the resulting dish and according to the hydrocolloid used. Let’s say you want to make spheres, this index will show you which hydrocolloids can be used (that’s right - there are other possiblities than sodium alginate) and list the example recipes.

tkerby: Some good tips there! These are exatly the kind of tips and hints I would like to include in a future update, for instance in a master recipe or in an introduction to lecithin. Using a flat container and baffling makes sense. It's quite interesting that the foaming works better with the blades than with a tilted or perforated disk. I wonder if this is true for all immersion blenders? I remember that the foam/air was very fragile, but this might be because I expected something that would be slightly more stable. KLwood: No plans to print it on paper for now. But feel free to download the pdf, print it and distribute it!

Jack, thanks a lot for many good suggestions! I agree that master recipes would be beneficial. For now readers would be advised to "cross read" the recipes and make up their own master recipe. I've made a note of your suggestions under b). Regarding non-gelatin espumas - do you have any recipes? (you mention carrot air) It was quite difficult to find good lecithin recipes - I've tried the Frozen parmesan air recipe and I must admit that it was not a huge success. This might be because my handheld immersion blender does not have the proper attachment for making airs (it has a knife, not a tilted disk). I did consider starch and flour, but I feel they are pretty well covered in other cookbooks. I will include them however if I find recipes that illustrate uncommon properties of these. Turkish Delight is certainly a good candidate. I'll look into that.

I've put together a collection of more than 100 recipes utilizing the full range of hydrocolloids that are becoming available to the average consumer. The collection is available for free download from: http://khymos.org/hydrocolloid-recipe-collection-v1.pdf (433 kB, 29 pages) Download it, use it and let me know if you have recipes that should be included in a future update! Here's what I've writting in the introduction:
