Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Caper Sauce for Fish
Ingredients
Directions
Combine the melted butter, veal gravy or jelly, essence of anchovies, and chili vinegar or cayenne in a bowl, then add the capers and mix well.
If you don't have gravy, substitute with mushroom catsup or Harvey's sauce, but note this will darken the sauce.
