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
Beat the butter until creamy.
Gradually add the powdered sugar and arrowroot while continuing to beat.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the butter mixture.
Add a few drops of your chosen essence and mix well.
Bake and serve
Pour the batter into a tin and bake at 350°F (175°C) until done, ensuring the outside doesn't burn.
Once baked, slice the cake, remove the outer crust, 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
- Creams with the sugar to give the cake richness and a tender crumb.
- Egg whites
- Whipped to stiff peaks, they trap air that lifts the cake and gives it its snowy lightness.
- Arrowroot
- Starch that makes the crumb fine and delicate, keeping it light and tender.
- Powdered sugar
- Dissolves easily into the butter, sweetening the cake and helping it brown lightly.
The step that matters
Folding the egg whites into the butter mixture. Stirring vigorously or overmixing deflates the whipped whites, removing the air that makes the cake light. Fold gently with a spatula until just combined.
Swap the arrowroot
How well each one fits the dish's main ingredients (butter, sugar, egg, lemon):
