Why it works: Lemon and pepper 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 ↓
Spinach Souffle
Ingredients
Directions
Prepare
Chop the cooked spinach very fine.
Add the melted butter, lemon juice, salt, pepper, and the yolks of the eggs.
Make the soufflé
Fold in the beaten egg whites until stiff.
Turn the mixture into a buttered baking dish or small molds.
Cover and poach in the oven or steam until firm: 30 to 40 minutes for a large mold, 25 to 30 minutes for small molds.
Serve
Serve with hot boiled dressing or drawn butter sauce, garnished with hard‑cooked eggs and lemon sections.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped in the mixture set into a light, airy structure when cooked.
- Spinach
- Provides the main body and flavour of the soufflé.
- Butter
- Adds richness and a smooth, tender texture to the mixture.
- Lemon juice
- Adds acidity that brightens the flavour of the spinach.
The step that matters
Folding in the beaten egg whites. Whites must be beaten until stiff and folded in gently. Deflating them loses the air that makes the soufflé rise and become light, so it may turn out dense.
Swap the spinach
