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
Mix the batter
Chop the cooked spinach very fine.
Add the melted butter, lemon juice, salt, and the yolks of the eggs.
Fold in the beaten egg whites until stiff.
Cook
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
- Whipped whites trap air that lifts the souffle, and the yolks enrich it as it sets.
- Spinach
- Provides the bulk, body and main flavour of the souffle.
- Melted butter
- Adds fat for richness and a smooth, tender texture.
- Lemon juice
- Adds acidity that brightens the mild flavour of the spinach.
The step that matters
Folding in the beaten egg whites. The air trapped in the whites is what raises the souffle as it sets. Folding gently keeps that air in, while overmixing deflates the whites and leaves the set souffle dense. Underfolded whites leave streaks of unmixed egg.
