Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roe Croquettes
Ingredients

Cool the roes.
Rub the roes into a loose, granulated mass.
Make the mixture

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roes of shad
- Forms the main body of the croquette, providing rich flavor and a granular texture.
- Mashed potato
- Adds starch and body, helping the mixture hold together when shaped.
- Drawn butter
- Adds fat and richness, keeping the filling moist and tender.
- Raw egg
- Binds the mixture so the rolls hold their shape while cooking.
- Cracker crumbs
- Form a crisp, golden, browned crust when fried.
The step that matters
Cool before shaping. The mixture must be almost cool before shaping, because a hot, soft filling will be too loose to hold its shape and may break apart in the hot dripping.
