Why it works: Onion and horseradish match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,784 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
To Stew Sturgeon
Ingredients
Directions
In a pot, combine gravy, salt, black pepper, sweet herbs, onions, horseradish, and vinegar.
Bring to a boil for a few minutes, then let it cool slightly.
Add the fish and gradually bring to a boil again.
Stew gently until the fish begins to break apart, then remove from heat and keep warm.
Strain the gravy and thicken it with butter.
Stir in the port or sherry, nutmeg, and lemon juice, and simmer until thickened.
Pour the sauce over the fish before serving.
