Update: The collection has been revised and is now available for download more than recipe, 73 pages, 1. Such substances include both polysaccharides and proteins which are capable of one or more of the following: thickening and gelling aqueous solutions, stabilizing foams, emulsions and dispersions and preventing crystallization of saturated water or sugar solutions. In the recent years there has been a tremendous interest in molecular gastronomy. One fortunate consequence of the increased interest in molecular gastronomy and hydrocolloids is that hydrocolloids that were previously only available to the food industry have become available in small quantities at a reasonable price. Malaran Disperse xanthan and sugar with blender, the syrup will become sticky and gooey but remains liquid.

Download it, use it and let me know if you have recipes that should be included in a future update! In the recent years there has been a tremendous interest in molecular gastronomy. One fortunate consequence of the increased interest in molecular gastronomy and hydrocolloids is that hydrocolloids that were previously only available to the food industry have become available in small quantities at a reasonable price.
A less fortunate consequence however is that many have come to regard molecular gastronomy as synonymous with the use of hydrocolloids to prepare foams and spheres. I should therefore emphasize that molecular gastronomy is not limited to the use of hydrocolloids and that it is not the intention of this collection of recipes to define molecular gastronomy.
When purchasing hydrocolloids, typically only a few recipes are included. Personally I like to browse several recipes to get an idea of the different possibilities when cooking. Therefore I have collected more than recipes which utilize hydrocolloids ranging from agar to xanthan. In addition to these some recipes with lecithin not technically a hydrocolloid have been included. Recipes for espumas that do not call for addition of gelatin or other thickening agents have also been included for completeness.
All recipes have been changed to SI units which are the ones preferred by the scientific community and hopefully soon by the cooks as well. As far as possible, brand names have been replaced by generic names. Most of the recipes have been edited and some have been shortened significantly.
In some recipes, obvious mistakes have been corrected. But unfortunately, the recipes have not been tested, so there is no guarantee that they actually work as intended and that the directions are complete, accurate and correct. The recipes have been collected from various printed and electronic sources and every attempt has been made to give the source of the recipes. Since recipes can neither be patented nor copyrighted, every reader should feel free to download, print, use, modify, distribute and further develop the recipes contained in this compilation.

Review in St. Louis Post-Dispatch. Review in Riverfront Times. See me on TV! I've wanted to find info on a lot of these techniques for some time now. Thank you so very much for sharing this! Examples from Midsummer House include Grapefruit and Champagne, Garlic and Bay leaf, cep, pea, strawberry, vanilla, coffee etc, the list is endless one the principle is established.
Other lecithin based are egg yolk based such as zabaglione If you allow them then dough might be considered as well. 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. 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 tried a lemon air last night and froze it using my Bamix immersion blender.
I actually found the blade was better than the tilted disc or the whisk disc perforated. The trick was to get the height in the liquid just right. Too low and you create a whirlpool destroying the forming foam. Too high and it splatters, also killing the foam.
Keeping the blender in a corner allowed the foam to gather elsewhere in the box. I placed a large spoon in the box near the blade to break up the flow. This allows bubbles to rise and stops them being destroyed. I found freezing to work but bubbles defrost really quickly and don't remain stable when they have defrosted. I think I added a bit too much lecethin when I was annoyed it wasnt foaming because whilst it tasted fresh when made, it picked up a slimy soapy taste and mouth feel when frozen.
Interestingly, my gourmet whip arrived last night and as I was cooking Thai curry noodles, I had spare coconut milk and tried the Pina Colada. Very surprised it worked as I was using fresh pressed pineapple juice and I thought the bromelain enzyme would stop the gelling process from working. I can only presume the juice may have been pasteurised by the supermarket. I have to say it was exceedingly tasty especially with double the rum, you couldn't taste it to start with and had the interesting effect of making me tipsy despite the fact I only had around a shot of alcohol total in the few glasses I made.
This is great! Thank you. I appreciate the detailed descriptions e. 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? KLwood: No plans to print it on paper for now. But feel free to download the pdf, print it and distribute it! It's kinda like wrestling a gorilla Martin, thanks so much for putting this together and making it available to all of us! I'm sure it was a lot of time and effort to do.
I'll be sure to distribute it to any of my students who are interested in this sort of thing. Several new recipes have been added now counting more than in total , including recipes with cornstarch, guar gum, gum arabic, konjac and locust bean gum.
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. Edit: I just checked out the new edition. It is totally awesome - probably the most comprehensive hydrocolloid resource anywhere in the world. Just to let you know that version 2. 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. Just a small note to let you know that I've just published an update of "Texture - A hydrocolloid recipe collection" version 2.
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?
You note on page 5 that not all the recipes are tested, let alone optimised. It might be helpful to note the distinction between those that are fully 'de-bugged' and those where you would particularly welcome feedback. Maybe marking recipes with some graphical symbol s to show their status? Its an amazing resource, well done! Back in 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. 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:. Remember to include the name of the recipe photographed and your name as it should appear under the picture.

Hydrocolloid Recipe Collection version 2.1 Released
Using hydrocolloids allows a chef create almost any shape and achieve almost any texture using food, all without compromising flavor. In the past, gums have gotten a bad rap among consumers, who perceive them as additives used by industrial food producers for economy and convenience; they can ease fabrication and make products that are cheaper, easier to ship, easier to freeze, and harder to spoil. However, as the number of chefs migrating hydrocolloids from additive to ingredient in the pursuit of creating better and more interesting food grows, so increases the number of savvy consumers who abandon prejudices against its usage. Hydrocolloids are large molecules that interact with water, and are defined as a type of mechanical mixture where one substance is dispersed evenly throughout water. A hydrocolloid has colloid particles spread throughout water and depending on the quantity of water available can behave as a gel or liquid. Many hydrocolloids can change their physical behavior and characteristics with the addition or elimination of heat.
