Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Venetian Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Combine the sugar and lemon rind, then mix with the egg yolks to form a paste.
Shape and bake
Roll the paste to less than ¼ inch thick and cut into 6 or 7 equal portions.
Place the portions on lightly floured or buttered baking tins.
Bake until firm, crisp, and pale brown.
If needed, stack the warm cakes and weigh them down to level.
Assemble and decorate
Once cooled, spread different preserves on each layer and stack them to form a cake.
Optionally, ice the top and decorate with pistachio nuts, colored sugar, or almond‑paste leaves.

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
- Pounded sugar
- Sweetens the paste and helps it hold together as a dough.
- Egg yolks
- Bind the sugar and rind into a rich paste that bakes firm and crisp.
- Preserves
- Add sweetness and moisture between the layers.
The step that matters
Bake until firm, crisp, and pale brown. Sugar and egg yolk paste can over-brown quickly at this low heat, and the cakes need enough drying to turn crisp rather than soft. Pulling them at the right colour keeps them pale and firm.

Fit is the average pairing score against sugar, egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
