Fat washing is a mixology technique in which you infuse fat into a liquid, and the fat separates and rises to the surface. The result is two flavorful products. The fat is infused with the flavor of the liquid, and the liquid is infused with the flavor from the fat. Mixologists like to fat wash various alcohols to add more depth, mouthfeel, and complexity to cocktails. Chefs can use the infused butter, duck fat or olive oil to make delicious sauces. In this video, Kikkoman Executive Chef Andrew Hunter shows us how to make fat washed citrus seasoned ponzu. Using the fat washed ponzu, he makes a delicate and aromatic beurre blanc served over roasted halibut.
