Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Ice Cream in a Savoy Biscuit
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a large bowl, combine the powdered sugar and flour, then sift them together.
Add the grated lemon rind and pounded almonds, mixing well with a wooden spoon.
Incorporate the egg yolks one at a time, mixing thoroughly after each addition. Beat the mixture for a few minutes until well combined.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the batter, a little at a time. Sift in the flour and stir gently until combined.
Bake and shape
Grease one or two molds and dust with powdered sugar.
Pour the batter into the molds and bake in a cool oven at 300°F (150°C), gradually increasing the heat.
Once baked, carefully turn the biscuits out of the molds and return them to the oven for 2-3 minutes.
Allow to cool, then cut the tops off straight and remove the insides in one piece.
Cut the insides into rusks about 3 inches long and 1 inch wide, and brown them in a gentle oven.
Serve
Fill the biscuit with ice cream or fruit-flavored water ice, replace the top, and garnish with the rusks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites and beaten yolks give the batter lift and a light, airy structure.
- Fine powdered sugar
- Sweetens the batter and helps give the biscuit its fine, tender crumb.
- Fine dry flour
- Provides the starch structure that sets the batter as it bakes.
- Lemon rind
- Adds aromatic citrus oil that flavors the batter.
The step that matters
Folding in the beaten egg whites. Folding gently, a little at a time, keeps the air bubbles in the whites intact. Overmixing deflates them, so the biscuit bakes up denser and less light.
