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 ↓
Baked Omelet with Greens
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the greens
Chop the kale very fine, using a meat chopper if possible.
Make the base
Melt the butter in a saucepan, add the flour, and cook for about 1 minute.
Add the milk while stirring constantly, and cook until the mixture is smooth and thick.
Stir in the chopped greens, egg yolks, and seasonings.
Bake and serve
Beat the egg whites until stiff and fold them into the mixture gently.
Pour the mixture into a buttered baking pan and bake at 300°F (150°C) for 30 minutes or until firm and brown.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites whipped to stiffness lift the mixture, and the yolks help set it as it bakes.
- Flour
- Cooked with melted butter, it forms a roux that thickens the liquid into a smooth base.
- Butter
- Fat that enriches the base and helps the baked surface brown.
- Greens
- Finely chopped kale adds body, flavour and moisture to the baked mixture.
- Milk
- Liquid that, heated with the roux, forms a smooth, thick base.
The step that matters
Fold the beaten egg whites gently. Whites beaten to stiff peaks hold air that makes the omelet rise. Vigorous stirring knocks that air out, leaving a dense, flat result.

Fit is the average pairing score against butter, flour, egg, milk, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
