Flavor pairing is a controversial* topic which I’ve blogged about many times in the past. In my last post I suggested that predicted aroma similarity may be a more precise term, and below is an attempt to illustrate predicted aroma similarity (of type 2d according to this classification) by using a color analogy. Let me explain a little first: The letters describe different foods and colors are used to illustrate the sum of the key odorants. The normal situation is that foods A and K (which are perceived as different because they are far apart in the alphabet) also have different colors meaning that they share few or no key odorants. A and B however are close in the alphabet and have similar colors, hence they share key odorants. In some cases foods that we think are very different (A and Z) may turn out to share several key odorants (i.e. have similar colors). The “flavor pairing hypothesis” is a way of finding the “Z” based on predict aroma similarity. I think one reason why we cannot always find the “Z” is that (more…)

You can tell that the days were packed during my visits to Belgium (The Flemish Primitives) and Denmark (Molecular gastronomy seminar) in March by the fact that I still blog about it in June. After the sous vide masterclass I attended a master class on taste technologies hosted by Quico Sosa (the man behind the Sosa company) and chef Dave De Belder. Many may frown upon flavors and their use in high end gastronomy, but anyone who considers using flavors as a shortcut to better cooking should rethink this as both successes and disasters are amplified (interestingly, Bruno Goussault said exactly the same about sous vide in the preceeding masterclass).

In haute cuisine, technology must be at the service of flavour and not otherwise. We must escape from the myth that everything was better in the past and also, that everything new is better. (“The technology of flavours”, Sosa ingredients)

Foamy strawberries with coriander (cilantro) from TGRWT #3 turned out to be a delicious combination. Could it possibly be a category 2d predicted aroma similarity?

As mentioned in my previous post about the flavor pairing presentation given by Wender Bredie as part of the Copenhagen seminar on molecular gastronomy I’m really happy that the topic has been brought into the scientific community. At the same time is has also become very clear to me that the term flavor pairing needs some clarification. First of all I have come to realize that the the term flavor pairing is slightly misleadning, and I wonder if aroma similarity perhaps is a more precise term. As I see it, today the term flavor pairing is used in a range of different ways: (more…)

Wender Bredie presented results from experiments designed to test the flavor pairing hypothesis

A topic that I was particularily excited to hear about at the molecular gastronomy seminar in Copenhagen was flavor pairing. Since Heston Blumenthal presented his white chocolate and caviar combination based on amines in 2002 and Francois Benzi of Firmenich the pork liver-jasmine combination based on indole the idea has been further elaborated by Bernard Lahousse and Lieven De Couvreur who launched the foodpairing website and by me in the TGRWT food blogging event. Despite the interest and fascination it is fair to say the flavor pairing is still controversial – see for instance the discussion with in particular Jorge Ruiz. What is clearly lacking in the field is a more stringent scientific approach (as well as someone with time, interest, a sensory panel and the money to finance the activities…). It was therefore great to hear that sensory science professor Wender Bredie together with PhD student Ditte Hartvig actually set out to test the flavor pairing hypothesis formulated as: if major volatiles are shared between two foods it may very well be that they go well together. To achieve this they used a sensory panel to assess the odor of food pairs mixed and unmixed. Bredie proposed that a hyper addition of odor intensities would perhaps be the holy grail of flavor pairing – that is if the intensity of the mixed odors would be more than the sum of the unmixed intensities. Or even better: if there would be a hyper additive effect on pleasantness.  (more…)

In my everday cooking sage is really underutilized. The only dish I can think of with sage that I’ve prepared during the last couple of years is potato gnocchi. So this was indeed the most likely candidate for experimentation in this month’s TGRWT #21. Potato gnocchi are one of those dishes that I suddenly feel a craving for, and I make it every now and then. When I get things right the gnocchi have a very light texture which fits nice with the melted butter and cheese. This time I decided to incorporate the peanuts into the gnocchi and apart from that stick to the original recipe.

While cooking I tried to chew some peanuts with a sage leaf, and this was a quite remarkable experience. The roasted peanut flavors blended into the sage, and the sensation was stronger than what is usually the case from the previous TGRWT rounds. When tasting sage by itself it will actually remind me of peanuts and vice versa. The last time I had a similar strong sensation was when combining roasted cauliflower with a cocoa agar gel.

It’s been a couple of months since the last round of “They go really well together” where food bloggers around the world explore food pairings based on similarities in their aroma profiles. The similarity is not based on the concentrations of the aroma components, but rather the odor impact of the components to the overall aroma (and in case you wondered: impact does vary with concentration, but it varies even more with the detection threshold). In other words, what this food pairing does is to point at two foods (which often may seem quite different) and say that these actually have something in common. And because of that it could be worthwhile to try and use them together when cooking. The 21st round of TGRWT is hosted by Greg over at Humbling attemts at creativity, and the foods to pair are sage and roasted peanuts. Head over to his announcement post for more details on how to participate. The deadline is June 1, so there is plenty of time for some creative cooking the next couple of weeks! If you’re not yet familiar with TGRWT you may want to have a look at some of the previous TGRWT rounds.

A small sprinkle of salt will suppress bitterness – and in some cases it can benefit the overall coffee flavor. I’ve tried it with an espresso and somehow it works, but it’s difficult to describe the flavor.

I prefer my coffee black, and politely decline when offered milk and sugar. However, if offered salt I would probably smile and say “Yes, please!” Salt???! It turns out that adding salt to coffee is not as weird as it may sound at first. There is a tradition for adding a pinch of salt to coffee in Northern Scandinavia, Sibir, Turkey and Hungary. And when available, such as in coastal areas where fresh water from rivers mixes with the salt sea, one would simply use brackish water when preparing coffee. This water typically has a salt content of 0.5-3%, which is lower than the average 3.5% in seawater. This results in a more intense taste and more foaming. And if living far from the sea, the Swedish food blogger Lisa Förare Winbladh let me know that in Northern Sweden one would deliberately add salt if using melt water from glaciers for making coffee. But tradition aside, is there a scientific explanation of this widespread tradition of preparing coffee with addition of salt?

Crycotuv – a combined vacuum chamber and super fast freezer with internal spray nozzle.

If I were to name a topic for this year’s Flemish Primitives event I guess gadgets would be it. I’ve already covered the high pressure processing in a previous post. Regrettably we were only shown pictures and movies of this machine (it is to large/complex to be brought on stage) but there was much more that would qualify for a post focusing on some of the gadgets presented.

Crycotuv
The most obscure machine in my opinion was the Crycotuv – a vacuum chamber which could be cooled to any desired temperature between -150 and 0 °C in seconds/minutes. (more…)

Again I was lucky that all the practical details worked out so I could attend this year’s Flemish Primitives in Brugge. For some one who’s not attended, it’s not so easy to grasp the concept and ideas behind The Flemish Primitives (TFP). And I admit, even though I’ve been there twice it’s not so easy to convey it in a short way. First of all the name is rather cryptic (unless you’re into art) as it refers to early Netherlandish painting. The link to food is described as follows by the organizers of the event (my highlights):

In the 15th and 16th century, ’The Flemish Primitives’ were masters in combining their talent with new techniques. Techniques they developed by interacting with other disciplines like manuscripting, sculpting, etc. This way of working changed the painting techniques in all of Western Europe forever. The event ‘The Flemish Primitives’ wants to continue in the same spirit. Respect for food products and beverages, the knowledge of the classic cooking techniques combined with a stimulation of new techniques and creativity. By promoting interaction between scientists, the world’s most famous chefs and artists, the event wants to deliver a creative boost for the food industry and gastronomy in Belgium and the world.

Considering last year’s sucess it was no big surprise that this year’s event was sold out (and the foyer of the Concertgebouw was equally full in the coffee breaks). And with the memories from last year I arrived in Brugge with great expectations. One main difference from previous years was that the scientific parts were much better integrated throughout the day. Scientists were on stage alongside the chefs, explaining their work. Also, contrary to last year’s back stage kitchen, they had now moved the kitchen onto the stage, flanked by a bar, some sofas and laboratory mezzanine. A good decision!

This month’s round of TGRWT is hosted by John Sconzo over at Docsconz, and the foods to pair this time are pumpkin and cooked chicken.* 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 19 rounds!

* In case you wondered why the link to the announcement posts includes lemon grass: There was some confusion regarding how to read the charts at the foodpairing website. The initial suggestion was to use pumpkin and lemon grass, but his has now been changed to pumpkin and cooked chicken.
