The Harvard School of Engineering and Applied Sciences (“SEAS”) and the Alícia Foundation have developed a new General Education science course, “Science and Cooking: From Haute Cuisine to the Science of Soft Matter”. The class is limited to currently enrolled Harvard undergrads, but the general public will have an opportunity to attend topic-related public lectures given by the guest chefs and faculty affiliated with the course. The lectures are not a replication of the course, but will consist of a brief introduction by Harvard professors followed by a broad-based talk by the chef. The first public lecture tomorrow features Harold McGee, Ferran Adria and José Andrés, so it would be well worth a visit if you live nearby. More info on venue, times and schedule here.

I believe most chemists are familiar with the “periodic videos” from the University of Nottingham, covering all the known chemical elements. The series features professor Martyn Poliakoff who’s grey hair is really worthy of a professor! They have now covered the complete periodic table of elements, and have even started to update some of their previously posted videos. There are also thematic videos as well as videos covering specific molecules appearing now. As a chemist I think the videos are great fun to watch since they show a number of exotic experiments I’ve never seen before combined with plenty of nice-to-know facts. I certainly recommend all these videos (for an overview, check out their website), but the reason I chose to blog about this is that I was delighted to find a number of more or less food related videos! These are definitely not going to make you a better cook. But some of them are quite amusing to watch, and you may even learn some chemistry as you go. But most of the food related videos are really just for fun
Egg coffee – a mild and refreshing drink that can be served warm as well as cold
I recently stumbled over “Norwegian egg coffee”. At first I thought it was a joke, but it turned out that this is indeed an “egg coffee” – coffee prepared with an egg! I have never heard about it here in Norway, but the fact that it’s popular among Americans of Scandinavian origin in the Midwest suggests that it could be something immigrants brought with them from Norway (feel free to fill me out on the historic origins of this!). I mentioned egg coffee to my mom, and although she had never heard of it before, she did mention that skin or swim bladders from fish were used when boiling coffee to help clearify it. In fact the Norwegian name for this – klareskinn – literally means “clearing skin”. The English name is isinglass (thank’s Rob!). Could it be that the fish skin originally used was replaced by eggs, perhaps due to a limited availability of fish in the Midwest? After all, both are good protein sources.

In addition to Modernist Cuisine and Keys to Good Cooking there are so many new books appearing this fall, so to save you from too many blog posts I’ve collected them here in a single posting. These are all books that I find interesting from my popular food science perspective combined with a strong interest for the actual cooking! The books are, in order of appearance: Read the rest of this entry »
“I’ve heard from many cooks that while they value the scope and depth of “On Food & Cooking,” when they need practical help with a specific technique or ingredient it’s often hard for them to locate the information. So my next book will be nothing but practical information and directions, concise and brief.”
I think it’s fair to say that Harold McGee, more than any other person I know of, has been very successful at distilling scientific work into a very readable and accessible form. He did this back in 1984 with the first edition of On food and cooking, and then again in 2004 with a more or less rewritten edition in 2004. A complete book with practical information rooted in science can easily become the single most useful book in your kitchen!
In Asia it is not uncommon to eat fruit with salt or even soy sauce. From my own experience, and via friends, I known that fruits such as mango, guava, honey dew melon, watermelon, nashi pears and papaya are eaten with salt. Interestingly salt is used both for ripe and unripe fruit – the latter is especially the case for mango and guava. With unripe fruit I can imagine that the primary motivation is reduction of bitterness. I’ve previously blogged aboutsalt and coffee and how salt in tonic water reduces bitterness – the mechanisms are the same. In addition to the bitterness suppression low concentrations of salt will enhance sweet taste. [1] This would certainly be an advantage in unripe fruit. In ripe fruit there is hardly any bitterness left (or at least I presume that is the case), so here the salt may serve a different funtion. Could it be to balance the sweet taste and give a more savory and complex flavor? Perhaps it could also be explained as increased sensing by contrast amplification? Read the rest of this entry »
When I wrote about Nathan Myhrvold’s book project in November he estimated the book to reach 1500 pages. But what originally started out as a 300-page book on sous vide has now, with the help of a 20-person team, grown to a total of 2200 pages spanning five volumes! Need I say more? Finally the long wait is over: The Modernist Cuisine: The Art and Science of Cooking is now available for pre-order at Amazon, and the expected release date is December 1st. One could almost be afraid that there will not be anything more to blog about here at Khymos as everything will be covered in Modernist Cuisine (but I know better – every previous talk about “end of science” has turned out to be more a starting point than a final destination)
Ferran Adrià says that “This book will change the way we understand the kitchen”, and according to Heston Blumenthal it’s “A fascinating overview of the techniques of modern gastronomy”. And if that’s not enough – take a look at this 26 minute video which guides you through the almost endless amount of high-tech equipment Nathan Myhrvold and his team have available. Oh boy, oh boy!
I have spent lazy summer days in a “Sommerhus” (e.g. “summer house”) in Denmark with my family and one thing I will share with you is the coffee I enjoyed every morning. My wife doesn’t drink black coffee, so to keep things as simple and easy as possible I brought my Aeropress and a glass of preground coffee (for obvious reasons I decided not to bring my coffee grinder, but I did use a nice coffee from Tim Wendelboe though). At home I have enough equipment to prepare coffee in a dozen ways, but none are as simple and fast as the Aeropress (well – maybe except for Nescafe, but does that count?). I would even dare to say that no other method of preparing coffee offers a better quality-price-convenience ratio! Read the rest of this entry »
