Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fried Fish
Ingredients
Directions
Prepare
Clean the fish well and cut into pieces about 2 by 4 inches.
Place the fish skin side down in a colander and sprinkle with coarse sea salt.
Let the fish stand for 1 hour or up to half a day if needed.
Fry
Heat the fat in a frying pan until hot.
Roll the fish in flour or cornmeal, then fry slowly until thoroughly cooked.
For extra flavor, dip in beaten egg and roll in cracker crumbs after flouring, if desired.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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, whose flesh cooks through and becomes flaky when fried.
- Coarse sea salt
- Draws out moisture from the fish and seasons it during the standing time.
- Flour or cornmeal
- Forms a dry coating that crisps and browns in the hot fat.
- Beaten egg
- Helps the crumb coating adhere and adds a little richness to the crust.
The step that matters
Frying slowly until thoroughly cooked. Frying too fast can brown the coating before the thick parts of the fish cook through. Slow, steady heat lets the interior reach doneness while the coating turns golden and crisp.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
