Why it works: Arrowroot and vanilla match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 242 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Snow Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter to a cream.
Gradually stir in the sugar, arrowroot, and vanilla essence.
Beat the egg whites to a froth and add them to the mixture.
Beat the entire mixture well for 30 minutes.
Place the batter in a shallow tin.
Sprinkle white sugar on top before baking.
Bake
Bake in a moderate oven at 350°F (175°C) for about 1 hour.
Do not allow to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a froth, they trap air that lifts the cake and gives it a light, airy crumb.
- Arrowroot
- Provides a fine, tender starch structure that gives the cake its delicate, snowy texture.
- Butter
- Creamed with the sugar to add richness, softness, and a tender crumb.
- White sugar
- Sweetens the cake and helps stabilise the batter's airy structure while it bakes.
The step that matters
Do not allow to brown. This cake relies on its pale, delicate structure. Over-browning from too much heat or baking too long dries the surface and adds bitter, toasted flavour, so the oven must be kept moderate and the cake watched closely.
Swap the arrowroot
How well each one fits the dish's main ingredients (butter, sugar, egg, vanilla):
- Sweet potatofits about as well
- Arrowrootthe original
- Capsicumfits less well
- Asparagusfits less well
Fit is the average pairing score against butter, sugar, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
