Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Croquettes of Shad Roe
Ingredients
Directions
Prepare the roe
Scald the shad roe in boiling salted water with vinegar for 15 minutes.
Transfer the roe to ice-cold water to stiffen and blanch.
Break apart the roe gently with the back of a spoon until it resembles tiny grains.
Make the custard
Combine hot milk, roux, salt, and pepper in a saucepan.
Cook the mixture for 3 minutes.
Add the roe to the mixture.
Cook for 2 more minutes after boiling.
Remove the mixture from heat.
Gradually mix the mixture with beaten eggs, adding seasoning, lemon juice, and anchovy paste.
Place the mixture in a pan over boiling water.
Stir the mixture for 3-4 minutes.
Pour the mixture onto a broad dish.
Let the mixture cool until stiff.
Shape and fry
Mold the cooled mixture into croquettes.
Roll the croquettes in egg and cracker dust.
Refrigerate the croquettes for at least 1 hour.
Fry the croquettes in deep cottolene until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roe (in the method)
- Provides the main flavor and the grainy, firm texture of the croquettes.
- Eggs
- Bind the mixture and set when heated, holding the croquettes together.
- White roux
- Thickens the hot milk so the mixture holds its shape when cooled.
- Hot milk
- Forms the creamy base that carries the roe and thickens with the roux.
- Cracker dust
- Forms a crisp, golden coating during frying.
The step that matters
Cool the mixture until stiff before shaping. The egg-enriched mixture must be fully set and chilled so it holds its shape; shaping it warm causes croquettes to slump and break apart in the fat.
