Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Smelts, to Fry
Ingredients
Directions
Prepare
Ensure the smelts are very fresh and clean them lightly without washing too much.
Dry the smelts with a cloth and lightly flour them.
Dip the floured smelts in the egg, then coat them with breadcrumbs.
Fry and serve
Heat the fat or oil until boiling and fry the smelts until they are a nice pale brown.
Drain the smelts on a piece of paper and serve with plain melted butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smelts
- The main fish, whose delicate flesh cooks quickly inside the coating.
- Egg
- Binds the flour and breadcrumbs so the coating adheres to the fish.
- Breadcrumbs
- Form a crisp, golden coating that browns when fried.
- Flour
- Dries the fish surface so the egg coating grips evenly.
The step that matters
Frying in boiling fat. The fat must be fully hot before the fish goes in. Hot fat sets the breadcrumb coating quickly, so it crisps and browns instead of absorbing grease and turning soggy.
