Why it works: Pecans and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,691 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Pecan Souffle
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
Preheat the oven to 300°F (150°C).
Make the batter
In a bowl, mix granulated sugar with the well-beaten yolks of the eggs.
Add ground pecans and vanilla extract to the mixture.
Gently fold in the stiffly beaten egg whites.
Bake
Pour the mixture into a greased pan and bake for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam, they trap air that lifts the souffle as it bakes.
- Egg yolks
- Enrich the batter and add richness and structure as they set in the oven.
- Ground pecans
- Add body, fat and nutty flavour to the batter.
- Granulated sugar
- Sweetens the batter and helps stabilise the yolks when beaten with them.
The step that matters
Gently fold in the stiffly beaten egg whites. Folding gently keeps the air trapped in the whipped whites. Stirring vigorously deflates the foam, so the souffle rises less and turns dense.
Swap the pecans
How well each one fits the dish's main ingredients (sugar, egg, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Pecansthe original
Fit is the average pairing score against sugar, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
