Five cardinal rules in cooking

Inspired by Martin's blog entry "Ten tips for practical molecular gastronomy", I came to remember Östen Dahlgren's five cardinal rules in cooking:

  1. Be critical of recipes
  2. Stop and think - should I really do [it like] this?
  3. Keep in mind how the heat is distributed/transferred
  4. Keep in mind what is soluble in what
  5. Taste while you're cooking - often
(my translation)

Dahlgren has written the book "Laga mat - Hur man gör og varför" ("Cooking - How to do it and why"), which is a Swedish counterpart to McGee's "On food and Cooking".
Dahlgren's list is a simpler version of the ten rules that Martin lists up. Although less comprehensive, the short list is easier to keep in mind whenever you're cooking, and I think that's a virtue. I could have commented further on each point, but I think I'll keep it short this time.
What is soluble in what? Blueberry juice in chili oil

Furthermore it seems to me that the various tips in Martin's list demand quite different degrees of knowledge and experience. "Learn how to control the texture of food" and "Learn how to control taste and flavor" demand quite a lot of either knowledge or experience (or both) from the cook. On the other hand, "Know what temperature you’re cooking at" doesn't demand much more than the skill of using a thermometer. Of course, Dahlgren's list also operates on different levels, but maybe less so than Martin's. Or is it maybe me seeing things a little too much through my own eyes here, being more accustomed to Dahlgren's rules knowing them for a longer time?

One of my personal favourites is by the way Martin's 9. tip, being imperative in science and science education: "Keep a written record of what you do! ".

Maybe should we go for a happy marriage, making one complete list for the Molecular Gastronomy enthusiasts and a shorter one for everyone else? A future post, either here or at Martin's blog, should certainly have two such differentiated lists. A joint venture?

A kindred spirit

My first experience with the annual ASE (The Association for Science Education) conference was at The University of Birmingham 3.-6. January. A paradox was that I had to go all the way to England to find that one of the most interesting experiences was to be a Swedish lecturer.

A packed programme with hoards of parallel sessions, spanning most thinkable and unthinkable science education issues; from the highly inspiring/enthusing to the one that give you the feeling "I never thought it was possible to completely ruin something so inherently fascinating". However, one experience left all of the other sessions in the shadows: Hans Persson at the Swedish National Centre for Education in Physics (and The Stockholm Institute of Education) had two sessions: "Creativity in the Science Classroom" and "Curious About Science?". His approach to science teaching was so fresh, vital and inspiring that the session ended in the audience giving standing ovations (the first time I've experienced such after a conference lecture).

What makes this special? First of all, the strong focus on students' interest/attitudes towards science in addition to the knowledge. Interest before knowledge, maybe. If you don't enjoy dealing with science, you won't learn much. Other key factors are having courage to be truly playful and enthusiastic, and utilising every aspect of everyday life to impart science. I also share his quite strong criticism of the kind of science teaching that is separated from everyday life, i.e. lab equipment which its sole purpose is for use in science education, but which doesn't exist anywhere else (note that this primarily applies to primary and secondary school, college/university level may be quite a different ballgame).

The other thing that makes this stand out is that he managed to convince me that he's got a firm foundation for this approach, possibly both theoretical/ideological and empiric, both from primary/secondary school and teacher training. His book on concept building is sure to find it's way to my bedside table soon (only in Swedish, unfortunately, but he's published books in English as well).

Anyway, I don't think I've seen such a fresh approach to science education during my five years in the game, and I decided to post this although strictly it doesn't deal with food and science education (although he touched in on that as well).

A visit at his web page, which bears the subtitle "How can we awaken interest in science and then keep that interest alive?", gives a small glimpse of his thoughts and work. I find this so important that I've put the link in the permanent links list in the right hand margin.
