Belgian Bacon Pudding Recipe From ‘Cognitive Cooking with Chef Watson’

The following is a recipe from “Cognitive Cooking with Chef Watson,” which is the result of a collaboration between IBM, which created the computer Watson, and the Institute of Culinary Education. Using a massive database of recipes and food chemical compounds, Watson created groups of ingredients that satisfied three metrics: surprising, pleasant, and synergy. A team of chefs, including James Briscione, director of culinary development at ICE, and Michael Laiskonis, creative director at ICE, would then create recipes using those ingredients. Here, Chef Watson creates a Belgian bacon pudding.

Bacon-flavored desserts are no longer uncommon, so we chose the popular ingredient as a launching point, in search of more unusual flavor pairings. Watson surprised us with mushroom, cumin, and caraway. The intent here was to present a decidedly sweet flavor, accented with smoky umami notes from the bacon and mushroom and balanced by the acidity of buttermilk. The dried fruits and olive oil-walnut financier provide textural contrast.

Pro Notes and Tips

Although there are no actual pieces of bacon in this dish, its smoky flavor is thoroughly extracted through an infusion process known as fat washing, a technique used by many chefs and mixologists. If ground walnut meal is unavailable, make your own by grinding ½ cup walnut pieces in a food processor with a portion of the confectioners sugar called for in the recipe.
