Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
To Fey Smelts
Ingredients
Directions
Prepare the smelts
Wash the smelts, cut off the fins, and dry with a cloth.
Lightly salt and flour the smelts.
Make the coating
Melt the butter in a pan and stir in the beaten eggs.
Dip the smelts into the egg and butter mixture, then roll them in grated bread crumbs.
Fry and serve
Plunge the smelts into boiling fat and fry until bright yellow-brown.
Serve on a napkin, garnished with fried parsley.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smelts
- The main fish; its delicate flesh cooks quickly once coated and fried.
- Eggs
- Bind the coating so the bread crumbs adhere to the fish and form a crust.
- Butter
- Adds richness and flavour to the egg mixture that clings to the fish.
- Grated bread crumbs
- Form a crisp, golden outer layer that browns when fried.
- Flour
- A thin dry layer that helps the egg mixture stick to the fish.
The step that matters
Frying in boiling fat. The fat must be hot enough to crisp and brown the crumb coating quickly. If it is too cool, the coating absorbs fat and turns greasy while the fish overcooks.
Swap the parsley
How well each one fits the dish's main ingredients (smelt, butter, egg, flour, bread):
- Capersfits better
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits less well
Fit is the average pairing score against smelt, butter, egg, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
