Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bean Soup
Ingredients
Directions
Make the soup base
In a pot, combine the remains of baked beans and enough water to thin the mixture.
Add a chopped onion and cook until the beans are soft and pulpy.
Pass the mixture through a colander to remove solids.
Finish the soup
If available, add stock or pieces of fresh meat for extra flavor.
Boil 1 pint of tomatoes.
Strain the boiled tomatoes and add them to the bean soup.
