Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Clam Soup
Ingredients
Directions
Prepare
Cut salt pork into very small squares and fry until light brown.
Add one large or two small onions cut very fine and cook about ten minutes.
Add two quarts of water and one quart of raw potatoes sliced; let it boil.
Add one can of clams.
Finish the soup
Mix one tablespoonful of flour with water, add one pint of milk, pour into the soup, and let it boil about five minutes.
Season with butter, pepper, salt, and Worcestershire sauce to taste.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions
| Ingredient | Portion assumed | kcal |

| Flour | 1 cup (125g) all-purpose | 455 |
| Potato | 1 medium (173g) baked | 161 |
| Milk | 1 cup (244ml) whole | 149 |
| Black Pepper | 1 tsp ground (2.3g) | 6 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they 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
- Flour
- Thickens the milk and broth into a smoother, slightly heavier soup.
- Milk
- Adds richness and creaminess to the broth.
- Potatoes
- Break down partly as they simmer, adding body and starch to the soup.
- Clams (in the method)
- Provide the main seafood flavour of the soup.
The step that matters
Mix the flour with water before adding it. Flour dropped straight into hot liquid clumps as its starch surface gels unevenly. Mixing it into cold water first disperses the particles so the soup thickens smoothly.
Swap the potato
How well each one fits the dish's main ingredients (flour, milk, pepper):
- Capsicumfits better
- Arrowrootfits about as well
- Potatothe original
- Parsnipfits about as well
Fit is the average pairing score against flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
