Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake's crumb together as it sets.
- Baking powder
- Releases gas in the batter, making the cake rise and lighten.
- Egg whites
- Whipped air trapped in the batter adds lightness and helps the cake rise.
- Butter
- Fat coats flour particles, giving a tender texture and rich flavour.
- Sugar
- Sweetens the cake and, creamed with butter, traps air that aids rising.
- Milk
- Adds moisture that hydrates the flour and helps form the batter.
The step that matters
Fold in the beaten egg whites gently. Whipped egg whites hold air that gives the cake its light rise. Vigorous stirring deflates them, leaving a dense, flat cake, so the whites should be folded in with a slow, lifting motion.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
