Texture updated and available for download

Saturday, February 15th, 2014


I’m happy to announce that a major update of “Texture – A hydrocolloid recipe collection” is now available for download. Version 3.0 of Texture features many new recipes, , more pictures (A big THANK YOU to all contributing photographers!), a new chapter on non-hydrocolloid gels + many minor additions and corrections. Given the many recent books about molecular gastronomy and modernist cuisine I have certainly asked myself: Is there a need for a revision of Texture? Since you read this I obviously landed on a “yes”. As a toolbox for chefs and amateur cooks I still believe that this collection is unique for several reasons: the ranking of recipes according to the amount of hydrocolloid used, the texture index and the total number of recipes (339 in total). To the best of my knowledge no other cook books have taken the same approach to collect and systemize recipes this way. And judging by the feedback I have received many chefs and food enthusiasts around the world have found Texture to be a useful resource in the kitchen (to which the 80.000 downloads from Khymos alone also testify). I do not regard Texture as a competitor to the numerous books available, but rather as a supplement. Inspiration for cooking is best sought elsewhere, but if Texture can inspire to experimentation with the texture of foods I believe it has fulfilled its mission.

“Texture” to be updated

Monday, December 30th, 2013


The collection of hydrocolloid recipes “Texture” (v. 2.3 available here) hasn’t been updated since 2010. But faithful readers have emailed me corrections and tips, notified me of typos and sent pictures – all of which I have incorporated. I’ve also noted that many have had problems viewing the pdf – I hope to fix that. But before I prepare a pdf of version 2.4 I would like to ask you a favor. Are there typos or errors you have noted, but not emailed too me yet? If so, please send them to me ASAP (either as a comment to this post or to webmaster (a) khymos dot org. And do you happen to have photos relevant to any of the recipes available? If you’re willing to share the pictures they could very well end up being included in the update. Of course I’d also love to hear your suggestions for further recipes that would complement and expand the collection.

Perfect egg yolks (part 2)

Saturday, April 23rd, 2011

Egg cooked for 40 min at 63.0 °C. The pictures were taken within 6 seconds and are shown in the order they were taken.

My immersion circulator is working again! And the first thing I decided to do was to cook eggs at 63.0 °C for 40, 60, 75, 110 and 155 min and show you the results. If you read my last blog post on Perfect egg yolks or have stumbled across the paper Culinary Biophysics: on the Nature of the 6X°C Egg you may recognize that these times correspond to egg yolks with textures similar to sweetened condensed milk, mayonnaise, honey, cookie icing and Marmite respectively. I used the iso-viscosity graph from the paper mentioned to determine the cooking times as shown below. (more…)

Perfect egg yolks

Monday, April 18th, 2011

Maybe I have a hangup on soft boiled eggs, but I’m deeply fascinated by how something simple as an egg can be transformed into such a wide range of textures. I’m talking about pure eggs – no other ingredients added. Playing around with temperature and time can result in some very interesting yolk textures – yolks that are neither soft nor hard, but somewhere inbetween. Two examples from the blogosphere are Chad Galliano’s 90 min @ 63.8 °C egg yolk sheets and David Barzelay’s 17 min @ 70.0 °C egg yolk cylinders (both bloggers giving credit to Ideas in food and Wylie Dufresne respectively).

In 2009 I wrote about my journey towards the perfect soft boiled eggs. Equipped with a formula I knew what I wanted, but it wasn’t so easy after all. Since then I’ve tried to model experimental data from Douglas Baldwin as well as data from my own measurements of egg yolk tempereatures when cooked sous vide (pictures of how I did this at the end of this blog post). I never got around to blog about the results, and now there’s no need for it anymore: The egg yolk problem has been solved! And the question that remains is: How we can utilize this in the kitchen?

The break through came this year (more…)

Update: Texture version 2.3

Tuesday, May 4th, 2010

An updated version of “Texture – A hydrocolloid recipe collection” is now available for download (version 2.3). The longer I work on this, the more I realize that it will never really “finish” – there’s always more to add. And believe me – my todo list is still quite long (and I even have some feedback which I haven’t had time to incorporate yet). But I thought that since it’s more than a year since the last update, it was about time to share with you the things that have been changed. Major changes and updates include:

Pictures: This is the biggest visual change! Some recipes are now equipped with pictures which may give you an idea of the texture AND they indicate that the recipe has indeed been tested. But I need your help to add more pictures to the recipe collection (please follow the link to read more about how you can contribute pictures)! And of course - a big thanks to those of you who have already contributed your pictures!

Recipes: Recipes have been added and the total number is about 310 now. I’m getting a little more picky now with regards to which recipes I add. Ideally each new recipe added now should illustrate something new.

I should mention that I’m very grateful for feedback from readers and users of this recipe collection. Thank you very much with helping me improve the document! If you find typos, wish to comment on something or have suggestions on how to improve the collection, please do not hesitate to write me an email at webmaster (at) khymos (.) org or just write a comment in the field below.

“Texture” to be updated with pictures

Sunday, January 3rd, 2010

Do you think “Texture” would benefit from some pictures? Now you are invited to contribute with your very own pictures to illustrate the recipes! (A big thank you to Chad Galliano who let me use his picture of foamed garlic oil!)

texture-frontpage-thumbA picture is worth a thousand words, and this is also true for recipes. Several of you 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:

TGRWT reminder and frozen rose foam

Monday, April 27th, 2009

rose-foam-spoon-2 Rose foam at room temperature

Just a small reminder that the deadline for the current round of TGRWT #17 is a little later than usual: May 8th. I took the picture above for last month’s TGRWT (where it was combined with chicken) and came to think that it actually qualifies for this month’s TGRWT as well. It’s rose foam on a spoon with apple, celery and almonds, and the foam is sprinkled with a little pepper.

As an experiment I tried to freeze the leftover rose foam and was quite surprised by the resulting texture. (more…)

TGRWT #16: Roasted chicken with rose foam

Tuesday, March 31st, 2009


For this month’s “They go really well together” event (TGRWT #16) hosted by Supernova Condensate I decided to leave the chicken untouched and focus on the rose component. I had long wanted to try Chad’s Lemon whip (which I’ve included in Texture) where lemon juice is thickened with xanthan and then whipped to a thick foam after addition of methyl cellulose. I started with water, a little sugar and about 10 g of rose water. Having added xanthan and methyl cellulose I tasted it and decided to double the amount of rose water, add some more sugar and add a little lemon juice for acidity. I can imagine that rose water comes in differents strengths so it’s advisable not to add all from the start.

Hydrocolloid recipe collection v.2.2

Friday, December 19th, 2008

An updated version of “Texture – A hydrocolloid recipe collection” is now available for download (version 2.2). There are two file sizes available: screen resolution (~1 MB) and high resolution for printing (~5 MB). Some recipes have been added bringing the total number up to about 270 recipes. Apart from this the version includes corrections of typos and updates of indexes and the supplier list. There is a new index for alcoholic preparations plus a small glossary. Again I should mention that I’m very grateful for feedback from readers and users of this recipe collection. Thank you very much with helping me improve the document! If you find typos, wish to comment on something or have suggestions on how to improve the collection, please do not hesitate to write me an email at webmaster (at) khymos (.) org or just write a comment in the field below.

Sous-vide cooking joy

Sunday, December 14th, 2008

Having received a real kitchen gadget before the weekend, I certainly had to do some sous-vide experiments. While shopping I looked specifically for meat that was already vacuum packed in plastic bags as I do not have a food saver. There is actually a decent selection available and I got a 1.5 kg roast beef and a chicken breast (a particularily nice one, bred according to the Label Rouge principles). The nice thing about the meat I got was that the packaging had temperature suggestions. Even though I have books and tables and access to the internet it’s always nice to have this information available exactly when and where you need it. And as I dropped the meat into the water bath it occured to me that this was so simple (not that I shun complex recipes), so clean (I’m not afraid of a messy kitchen) and so convenient (I’m not at all a fan of fast food) that given the expected end result this is probably how very many people will prepare their meat in a not to distant future! So to all farmers, butchers and producers of immersion circulators – I hope you read this and act accordingly ;)
