Why it works: Arrowroot and lemon match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Snow Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream the butter in a bowl.
Gradually add the powdered sugar and arrowroot while beating continuously.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the mixture.
Add a few drops of your chosen essence and beat for 20 minutes.
Bake and serve
Pour the batter into a tin and bake in a moderate oven at 350°F (175°C) until cooked through.
Once baked, slice the cake and dust with powdered sugar before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender, melt-in-the-mouth crumb.
- Arrowroot
- Starch that gives a light, fine, tender texture in place of wheat flour.
- Eggs
- Whites trap air for lift and structure; yolks add richness and binding.
- Powdered sugar
- Sweetens the cake and its fine texture helps create a smooth, delicate crumb.
The step that matters
Fold the egg whites gently. Whipped egg whites trap air that lifts the cake. Stirring hard or overmixing knocks that air out, leaving a dense, flat result.
Swap the arrowroot
How well each one fits the dish's main ingredients (butter, sugar, egg, lemon):
- Asparagusfits better
- Leekfits about as well
- Shallotfits about as well
- Arrowrootthe original
Fit is the average pairing score against butter, sugar, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
