Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Shrimp Salad
Ingredients
Directions
Marinate shrimp with salt, pepper, and lemon juice.
Mix marinated shrimp with mayonnaise and serve on lettuce leaves.
To make jelly, dissolve gelatin in water and mix with lemon juice.
Wet individual molds and pour a little jelly into the bottom of each.
Add several shrimp to each mold, then pour more jelly to cover.
Place molds in a cold place to harden.
To serve, turn out the molds onto lettuce leaves, cover with mayonnaise, and garnish with two or three shrimp.
