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 ↓
Almond Bars
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.
Shape the dough
In a large bowl, mix sugar, flour, eggs, ammonia, and chopped almonds until a dough forms.
Roll the dough out on a floured surface to about 1 inch thick and 2 inches wide.
Cut the dough into slices ½ inch thick with a sharp knife.
Place the slices on baking pans with the cut side facing up.
Glaze and bake
Brush the tops with beaten egg.
Bake in a slow oven at 300°F (150°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough together and sets as it bakes.
- Sugar
- Adds sweetness and helps the surface brown as it bakes.
- Eggs
- Bind the dough and, brushed on top, help the surface turn golden.
- Chopped almonds
- Add nutty flavor and a bit of texture to the bars.
The step that matters
Bake in a slow oven until golden. A low oven dries the slices gradually, so they set through without scorching. Sugar and the egg glaze brown quickly, so the color is a guide to doneness; too long and the bars turn hard and dry.
