Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Finger Cakes
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Beat the eggs very light.
Add the sugar, reserving 1 tablespoon.
Sift in the cream of tartar, baking soda, and salt.
Stir in enough flour to form a stiff dough.
Shape and bake
Roll the dough very thin and sprinkle with the reserved sugar.
Cut the dough into strips about the width of a finger.
Place the strips on a baking pan without letting them touch.
Bake in a 400°F (200°C) oven, watching closely to prevent scorching.
Add the vanilla to the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and moisture, and trap air when beaten to give lightness.
- Granulated sugar
- Adds sweetness and helps the surface brown as the cakes bake.
- Cream of tartar
- Acidifies the batter, stabilizing the beaten eggs and helping the baking soda react.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the cakes rise.
- Flour
- Forms the gluten network that gives the dough its structure and shape.
- Vanilla
- Adds aroma that rounds out the flavor of the finished cakes.
The step that matters
Watching the bake. Rolled very thin, the strips have little mass and brown quickly once in the hot oven. Sugar on the surface caramelizes fast, so they can scorch in minutes. Checking them closely and removing them as soon as they turn golden prevents bitter, burnt edges.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, cream, flour):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, sugar, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
