Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Creamed Perch-pike with Bacon Larding
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Mix the butter, sour cream, chopped onion, and lemon juice in a bowl.
Smear the mixture over the cleaned, bacon-larded perch-pike.
Bake and serve
Place the fish in a fire-proof dish and bake in a hot oven (400°F / 200°C) until half-done.
Add more sour cream and continue baking until well done.
Serve in the fire-proof dish with buttered potatoes and lemon slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour cream
- Forms a rich, creamy coating that keeps the fish moist as it bakes.
- Bacon
- Larding melts fat through the fish, adding moisture and savory flavor while it cooks.
- Onion
- Adds aromatic sweetness and flavor to the creamy coating as it cooks.
- Butter
- Adds fat that enriches the coating and helps it brown gently in the oven.
The step that matters
Adding more sour cream before finishing the bake. Sour cream can curdle or separate when exposed to high heat for long periods. Adding it partway through and baking only until the fish is well done helps keep the coating smooth and the fish moist.
