Heavy Hands
Continuing with my Valentine's Day Trio, course two was a preparation of the classic pairing of chocolate with orange. In this case, we made it two ways, once as a cocktail and once as a macaron. The macaron, pictured below, was a collaboration with my friend Johan, who was instrumental in designing this series.
For the base of this drink, I used a cocoa nib liqueur, which I have made before, but which I have now updated with a modern technique. The diffusion of sous vide immersion circulators to home cooks has opened up many exciting new possibilities for those who wish to keep it craft. I made this liqueur in a mere two hours, by cooking 6 oz of cocoa nibs in 375 ml of vodka at 60C for ninety minutes. I then strained out the nibs and boiled them in simple syrup for a few more minutes. This is the classic alcohol+water extraction.I combined the syrup into the infusion according my palate, and allowed it to rest for three days. In this time, the flavors of the syrup and the alcohol will meld together, resulting in a much softer flavor. If you were to taste it immediately after combining, you would find a harsh ethanol note on the backend.
This recipe, despite the fancy ingredients, is really just a take on Jeffrey Morgenthaler's Amaretto sour. We combine a liqueur base with egg whites and an acidic juice, then use an immersion blender to emulsify the egg white.
There is a small twist, however. Blood oranges, at the peak of their season right now, are not very acidic. They lack the acidity needed to form a stable foam out of egg whites, and as a result, they are not sour enough to balance a sweet chocolate liqueur. The answer to both of these problems is the same; powdered citric acid.
If you can master acidity, you can master cocktail creation. Acidity is the lynch pin of the drink, acidity is life. I slowly blended citric acid into my blood orange juice until it was approximately as sour as lemon juice.
Heavy-Hands
1.5 oz homemade cocoa nib liqueur
1.5 oz blood orange juice
.5 oz egg white
.25 oz simple syrup
Powdered citric acid to taste
Emulsify with a stick blender and then shake gently over ice.
Strain only with a hawthorne strainer into a cocktail glass and garnish by dropping chocolate bitters into the foam and then turning them into hearts with a toothpick.
Serve with a chocolate orange macaron and a mandarin orange.
Cheers.
