Amrita of Le Petite Boulanger has announced the foods to pair for the fifth round: chocolate and meat! And in case you didn’t notice, Dennis has written an excellent summary of the mustard-mint recipes of round four.
I was not able to figure out which odorants actually formed the basis for the mustard-mint pairing (and perhaps there is none… as I’ve touched upon before, some of the data is hard to come at so it’s difficult to check all the entries of my compiled list). At M’s blog however you can find more info on the cold receptors which are triggered by both mint and mustard.
Fortunately data for chocolate and meat is available: odor activity values for cocoa and flavour dilution values for boiled beef and roasted beef. All flavour compounds were ranked and compounds given the same color coding as before. As you can see, there is considerable overlap between chocolate and meat.
And here’s what the molecules that are found both in cocoa and beef look like. Notice that this pairing is dominated by furanones and pyrazines. The molecules are ranked according the the odor activity values in cocoa.
