Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Crab Stew
Ingredients
Directions
Prepare the stew
Shred the crabs and boil the sweet milk in a pot.
Add 1 tablespoon of butter and ½ teaspoon of black pepper to the milk.
Once boiling, add the shredded crabs and heat thoroughly.
Stir in the juice of 2 lemons and ⅓ cup of sherry, then serve.
Make the roux and finish
In a separate pan, melt 1 tablespoon of butter and mix in 1 tablespoon of flour until browned.
Add the strained tomatoes, chopped celery, red pepper, and salt to taste.
Incorporate the breasts of the cleaned crabs and cook for 5 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crabs
- Provide the main protein and sweet, delicate meat that forms the body of the stew.
- Sweet milk
- Forms the creamy liquid base that gives the stew its rich, smooth texture.
- Flour
- Thickens the butter fat into a roux, helping give the stew body.
- Lemons
- Add bright acidity that cuts the richness of the milk and butter.
- Sherry
- Adds acidity and a fragrant, nutty depth to the stew.
- Tomatoes
- Add acidity, color and a light tang to the stew.
The step that matters
Adding the lemon juice and sherry to hot milk. Acid can curdle or separate milk proteins when added to very hot dairy, so stir gently and keep the heat moderate once the acid goes in.
