Name: Potato Dressing
Ingredients: 2 cups hot mashed potatoes; 4 tablespoons cream; 1 teaspoon grated onion or juice; 1 tablespoon chopped parsley; 1 teaspoon black pepper; 1 tablespoon butter; 1 teaspoon salt; 2 egg yolks

Why it works: Parsley and pepper 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 ↓

Egg yolks: Bind the mixture and add richness and structure as they set with heat.
Cream: Adds moisture and richness, keeping the dressing soft and smooth.
Butter: Adds fat for flavor and a smoother, richer texture.
