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

Oven, in the book's wordsA cool oven

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 lemon zest 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, whip the egg whites to stiff peaks.
Gently fold the whipped egg whites into the batter, adding a little at a time.
Sift in the flour and fold it in gently until just combined.

Bake the biscuits

Grease one or two molds and dust them 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.

Finish and serve

Allow to cool, then cut the tops off straight and hollow out the insides, cutting the removed part into rusks.
Brown the rusks in a gentle oven.
Fill the hollowed biscuits with ice cream or fruit-flavored water ice, replace the tops, and garnish with the rusks.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs: Whipped whites give the batter lift and an airy, delicate structure as it bakes.
Fine powdered sugar: Sweetens the batter and helps give the biscuit a fine, tender crumb.
Fine dry flour: Provides the structure that holds the biscuit together after baking.
Lemon zest: Adds bright aromatic oils that flavour the batter.

The step that matters

Folding in the egg whites. Whites hold air only if they are whipped to stiff peaks and folded gently. Overmixing knocks out the air, so the biscuits bake flat and dense.
