Why it works: Lettuce and spinach match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 427 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
A Pepper-pot, to Be Served in a Tureen
Ingredients
Directions
Prepare
In a large pot, bring 3 quarts of water to a boil.
Add chopped seasonal vegetables and the meat (mutton or fowl) along with pickled pork.
Skim the surface when it first boils, then reduce heat and simmer until the meat is tender.
Finish the soup
Stir in a small quantity of rice with the meat.
Half an hour before serving, add the shelled lobster or crab.
Season with salt and Cayenne pepper to taste.
If fat rises, skim it off and mix ½ cup of water with a little flour to thicken the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck of mutton or fowl
- Provides rich meat flavour and gelatin that gives the broth body as it simmers.
- Pickled pork
- Adds salty, savoury depth and fat that enriches the broth.
- Lobster or crab
- Adds sweet seafood flavour and tender pieces to the finished soup.
- Rice
- Absorbs liquid and softens, thickening the soup slightly as it cooks.
- Flour
- Starch that thickens the liquid when mixed with water and stirred in.
The step that matters
Adding the flour and water mixture. Flour must be mixed smoothly with cold water before being stirred into hot soup; added dry or lumpy, it clumps and never thickens evenly. Starch swells and thickens only when the liquid is simmering.
