Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Shad-roe Croquettes
Ingredients
Directions
Poach the roe
Wash the shad roes.
Place them in a saucepan with salted boiling water.
Cover the saucepan and simmer for 15 minutes.
Remove from heat.
Take off the fine skin and mash the shad roes.
Make the binder
Bring the cream to a boil.
Rub the butter and flour together over low heat without browning.
Gradually stir in the boiling cream and boil for 3 minutes until very thick.
Remove from heat and stir in the egg yolks while still boiling.
Mix and shape
Add the mashed shad roes, lemon juice, parsley, nutmeg, cayenne, salt, and pepper, and mix well.
Spread on a dish to cool.
Once cool, flour your hands and form the mixture into croquettes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roes
- Provide the main body and rich, delicate flavor of the croquettes.
- Cream
- Makes the base thick and moist when boiled into the flour mixture.
- Butter
- Enriches the binder and adds richness along with the flour.
- Flour
- Thickens the butter and cream into a sauce that holds the mixture together.
- Egg yolks
- Stirred into the hot binder to add richness and help bind the mixture.
- Egg whites
- Used for dipping so the bread crumbs adhere to the croquettes.
The step that matters
Boil the binder until very thick. The flour must be cooked fully in the boiling cream to thicken the mixture. If it is undercooked, the mixture stays loose and the croquettes will not hold their shape. Cooling fully before shaping also firms it up.
