Why it works: Pepper and parsley 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 ↓
Omelet and Shad Roes
Ingredients
Directions
Make the shad roe filling
Heat the butter in a saucepan.
Stir in the shad roes, salt, grated onion, cayenne, and parsley until heated through.
Add the milk (or cream) and baking soda. Cook for 3 minutes and keep warm over boiling water.
Make the omelet
Beat the eggs for 1 minute. Add the cream, salt, and pepper.
Pour the egg mixture into a hot omelet pan with hissing butter.
Shake the pan until the omelet is set.
Pour the shad roe mixture on top.
Fold the omelet over and serve.

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 flavor and rich, tender texture inside the omelet.
- Eggs
- Set when heated to form the structure that holds the filling.
- Butter
- Adds richness and flavor and helps keep the omelet from sticking.
- Milk or cream
- Adds moisture and softness to the filling and the eggs.
- Baking soda
- Raises the pH slightly, which can help the filling stay tender.
The step that matters
Shake the pan until the omelet is set. Eggs set quickly in a hot pan; shaking keeps the surface moving so curds stay tender instead of over-cooking into a tough, dry layer before the filling is added.
