Ingredients: 8 ounces butter, softened; 2 pounds all-purpose flour; ½ pound brown sugar; 2 ounces powdered ginger; ½ ounce ground caraway seeds; 2 pounds treacle (or molasses); 3 eggs, well whisked

Why it works: Flour and caraway match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,435 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
