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
Prepare the roe
Wash the shad roes and place them in a saucepan with salted boiling water. Cover and simmer for 15 minutes.
Remove from heat, take off the fine skin, and mash the shad roes.
Make the custard base
Bring the cream to a boil. In a separate pan, 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 2 egg yolks while still boiling.
Add the mashed shad roes, lemon juice, parsley, salt, pepper, nutmeg, and cayenne. Mix well and spread on a dish to cool.
Shape, coat and fry
Once cool, flour your hands and form the mixture into croquettes about 1 x 2 inches.
Dip each croquette in egg whites, then coat with bread crumbs. Let them stand in the refrigerator for at least 1 hour.
Fry the croquettes in boiling lard until golden brown. Drain on folded paper.
Serve
Serve on a fancy-cut paper or folded napkin, garnished with parsley and lemon.

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 flavour and a soft, flaky body that forms the croquette filling.
- Butter and flour
- Form a roux that thickens the cream into a firm base that holds the mixture together.
- Cream
- Adds richness and moisture, making the thickened base smooth and tender.
- Egg yolks
- Stir into the hot base to enrich it and help it set firm when cooled.
- Egg whites
- Act as a binding coat so bread crumbs adhere evenly before frying.
- Bread crumbs
- Form a crisp, golden outer crust when the croquettes are fried.
The step that matters
Cool the mixture fully before shaping. A warm, loose mixture will not hold its shape and can crack or slump. Cooling lets the thickened base firm up so the croquettes keep their form through coating and frying.
