Why it works: Lettuce and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,562 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Shad Roe Salad
Ingredients
Directions
Poach the roe
Wash the shad roes and place them in a saucepan.
Cover with boiling water and add salt.
Cover the saucepan and simmer gently for 20 minutes without boiling.
Carefully lift the roes from the water and let them cool completely.
Remove the outer skin and slice the roe thinly with a silver knife.
Serve
Place a slice of onion in the center of a dish and arrange crisp lettuce leaves around it.
Heap the sliced shad roe in the center and serve with a bowl of mayonnaise dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roes
- Provides the main body and rich, delicate flavor of the salad.
- Mayonnaise dressing
- Adds fat and creaminess, keeping the sliced roe moist and rich.
The step that matters
Simmer gently without boiling. Shad roe is delicate and rich in egg protein. A rolling boil can toughen the protein and break the roes apart, while gentle simmering cooks them evenly and keeps them tender and intact.
