Name: Composition Cake
Ingredients: two pounds of raisins; one cup of molasses; one cup of milk; one teaspoonful of saleratus; six coffee cups of flour; six eggs

Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
