Why it works: Tomato and pepper match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 17,913 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: egg, walnut
Directions
Make the tomato base
Stew until tender 1 quart tomatoes either raw or canned.
Strain.
Put back on the fire and add a pinch of soda, salt and pepper to taste, butter the size of an egg, and 3 tablespoons rolled crackers.
Take from the fire, and stir in 1 quart scalding hot milk.
Serve immediately.
Make the milk version
Stew 1 pint milk with a little chopped celery.
Stew 1 can strained tomatoes 15 minutes with butter size of a walnut, salt and pepper to taste, and a pinch of sugar.
When ready to serve, stir into the hot milk, and serve immediately.
Cook and strain 5 good sized tomatoes.
Stew 5 minutes with a pinch of soda.
Season with 1 tablespoon butter, salt, pepper and celery salt.

Milk and sugar share little aroma chemistry, yet 77,855 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and acidic tomato flavour of the soup.
- Milk
- Adds creaminess and mellows the tomato acidity into a smooth soup.
- Rolled crackers
- Thicken the soup slightly by absorbing liquid and adding body.
- Butter (in the method)
- Adds richness and a smooth, rounded mouthfeel to the soup.
- Baking soda
- Neutralises some tomato acidity so the milk is less likely to curdle.
The step that matters
Adding the milk to the tomatoes. Tomatoes are acidic, and when hot acidic liquid meets milk the milk proteins can curdle. Keep the milk hot rather than boiling, add it at the end, and serve right away to keep the soup smooth.
