Miss Silvia is full of surprises! She’s been around the house for a year, but only now did she reveal one of her hidden capabilities. Did you know that you can make scrambled eggs with the steam wand of your espresso machine? Me neither. It’s a brilliant idea and one can wonder why no one has done this before. I mean, espresso machines have been around for a while. And as it turns out – according to Kelly’s comment below this was done in San Francisco back in the 90’s. It seems as if the credits for rediscovering these scrambled eggs should go to Chef Jody Williams (and thanks to Jessica at FoodMayhem for posting this). I’ve tried it several times and it works very well. I’d even say that this gives you another reason to purchase an espresso machine with a proper steam wand! Many other reasons can be found in my first post about Miss Silvia. (more…)

A sourd dough bread made from a spontaneous starter

After 7 days of feeding my sour dough starter “took off” and was ready for baking. Even with a water bath set to 28 °C it took longer than expected. I started off with 100% hydration as this is convenient when you have to feed your starter frequently. Using only whole grain rye flour and water, I fed my starter every 12 hours (I’ve included details of the “feeding schedule” at the end of this post). This time interval is based on the growth cycle of yeast, where the yeast after an exponential growth phase reaches a plateau after 8-12 hours. This is the best time for feeding the starter.

There seems to be a consensus that a wet starter (more…)

This post is mainly of interest to readers who understand Norwegian. I post this because I recently updated Khymos with a couple of pages of special interest for people in Scandinavia. I’ve also recently held several presentations to Norwegian audiences, and in this respect there are some pages in particular that I would like to point them to (such as local suppliers, books etc.). Therefore the rest of the post is in Norwegian, but I can assure you that I will continue to blog in English

Just a short note to let you know that there were 30 submissions to the last round of They Go Really Well Together (TGRWT #18) which featured plum and blue cheese. Aidan Brooks summed it all up in a round-up which was fun to read And in case you didn’t notice, there is a TGRWT tab in the menu bar – click it and you’ll see links to all the previous announcements and round-ups.

Last year’s book bonanza (Remember The Big Fat Duck Cookbook, Alinea and Under pressure right? Not to mention BakeWise, The Flavor Bible (not science, but I love their systematic approach), Cooking – The Quintessential Art, A day at el Bulli, the bilingual Sous-Vide, the German Verwegen Kochen and the Danish Molekylær gastronomi – did I miss any?) will be difficult to beat, but several interesting books will appear this fall as well. It’s as if this field is exploding with books now. When I first set up the webpages which later evolved into Khymos only a handful of books were available (you can travel back in time and view the single page from 2003 – only in Norwegian, sorry), but even I have a hard time now keeping track with all the books which cover the interesting intersection between cooking and science, aka molecular gastronomy. Sometimes I think – is this book really necessary? Do we need it? What does it add? But addicted as I am, I can’t help it – so I’ll probably get hold of most of these books as they become available

This month’s round of TGRWT is hosted by Pablo over at Medellitin, and the foods to pair this time are tomato and black tea. As always you can find instructions on how to participate in the announcement post. If you are new to TGRWT (which stands for They Go Really Well Together), check out the round-ups of the previous 18 rounds! And if you are chemically inclined, you may want to read on to learn more about the compounds behind this months pairing.

For TGRWT #18 hosted by Aidan Brooks I decided to use puff pastry dough and laminate some Norwegian blue cheese, “Norzola” (made to mimic Gorgonzola) between two layers and roll them out. To accompany this I made a plum reduction with my two favorite spices, star anis and ginger. I should also mention that I tried the very simplest combination of plum and gorgonzola as well: a simple slice of bread with some Gorgonzola and a thick slice of a blue plum. This was very delicious – and takes absolutely no time to prepare.

Finally it’s time for a new round of TGRWT. It’s the 18th round and the host this time is Aidan Brooks, a trainee chef who works in Spain. In his blog he’s touched upon flavor pairing several times and also wrote a blog post on the same topic for “Word of mouth”, the food blog of The Guardian. The foods to pair this time are plum and blue cheese, and as usual you can read more about how to participate in the announcement post. The deadline for submissions is September 1st.

TGRWT is not a competition, but Aidan wanted to add a little competitive element to round of the meal. (more…)

The Canadian sommerlier François Chartier (he has an extensive website featuring several blogs, including a section named Sommellerie moléculaire) is out with a new book on food and wine pairing. It’s not just another (superfluous) book on the subject. As the title Papilles et molécules (= Tastebuds and Molecules, unfortunately not available in English) suggests there is some science involved. It turns out in fact that he has applied the principles of flavor pairing to food and wine. With help from Richard Béliveau from Agriculture and Agri-Food Canada and Martin Loignon from PerkinElmer he has analyzed wines and food and comes up with the following suggestions for lamb, as described in the article “Chemistry-set wine pairing”:

As I mentioned in the post about the exciting color chemistry of nocino I picked some unripe walnuts last year in August when visiting family in Germany. These walnuts were in fact a little to ripe to make nocino from. Preferably the walnuts should be picked end of June when you can still push a knitting pin through the center. Mine were stone hard, but I decided to give it a try anyway, and it shure was worth the bottle of vodka! I checked a couple of recipes and found that many use cinnamon and cloves together with lemon (with peel). I figured I also wanted to try star anise and proceeded with two batches.

Attempt to make a sourdough starter using dried apricots, using my immersion circulator for temperature control. I got some bubbling yeast activity, but the final bread dough never rose properly.

Inspired by the Swedish bread blog Pain de Martin which I recently discovered I decided it was time to have a go at sourdough breads! Although one of my favorite types of bread it’s a long time since I gave it a try and even longer since I actually succeeded. Leaving apple peel covered with water for two weeks in a cool place (15 °C) I got a light apple cider which I used to make a starter some years ago. I followed a recipe from the Norwegian artisan bakery Åpent bakeri and it gave a marvelous bread. But since then I’ve tried to repeat this twice without success. No wonder that even Rose Levy Beranbaum in her book “The Bread Bible” writes that she didn’t intend to include a chapter on sourdough at all. There’s no doubt that sourdoughs are tricky, but I was a litte surprised and disappointed that someone who sets of to write a 600+ page book on bread even considered to skip sourdough… Luckily she changed her mind and the introduction has a fascinating nice-to-know fact: 1 g flour contains about 320 lactic acid bacteria and 13000 yeast cells!

I believe one the reasons why sourdoughs seem to live their own lifes sometimes is that they need to be kept in a warm place. My kitchen isn’t that warm so I figured it was time to use my immersion circulator and give sourdough another chance (who says you can only use immersion circulators for sous vide anyway? – I think my next project will be to make yoghurt!). With a thermostated water bath keeping a sourdough starter at constant temperature is as easy as 1-2-3. But surprisingly I haven’t seen any blogposts yet from people using their sous vide water baths for sourdough starters (although some have built their own water baths for this purpose using aquarium equipment).

Just a quick note to point you to the new blog “Cooking issues” featuring Dave Arnold and Nils Norén from the French Culinary Institute. In addition to posts inspired by ongoing activities at the FCI they have a comprehensive primer on the use of rotavaps in the kitchen (including several recipe suggestions!). Highly recommended!

Last year, while visiting family in Germany, I decided to pick some walnuts to bring home to Norway. They were not ripe, which was good, because I was planning to make nocino, a walnut liqueur. You can easily find a number of recipes by googling and there is also a nocino-thread over at eGullet.

What fascinated me the first time a saw nocino mentioned in a book about liqueurs was the nearly black color. Many recipes comment that after steeping, the liquid looks more like used motor oil than something edible. The color is really amazing and I also observed that most recipes recommended the use of gloves as the stains from the unripe walnuts would not easily come off. The juice from the walnuts is a light yellow green color to start with, but when exposed to air it quickly turns dark brown. Color chemistry is always fascinating and I couldn’t resist the temptation to investigate this further. (more…)

As I mentioned in the previous post I put the leftover rose froam from TGRWT #16 in the freezer and was surprised by the result. Inspired by this I thought I would extend this and substitute apple juice for water for TGRWT #17. As apple juice is quite sweet I started off with 20 g sugar, but once frozen it lacked sweetness and even was a litte icy, so I upped the amount to 40 g. The picture above may suggest that the foam could be served for dessert, but read the verdict before you make huge amounts of the foam.

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…)
