Why it works: Carrot and tomato match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,606 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Appledore Bean Soup
Ingredients
Directions
Soak the beans overnight in cold water to cover.
In the morning, drain the beans and add fresh cold water.
Bring to a boil and cook until soft, then rub through a sieve.

Remove the vegetables, add flour and salt, and stir into the boiling soup.
Add milk and tomato catsup, reheat, strain, and add the remaining butter in small pieces.
