Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Fish Bisque
Ingredients
Directions
Make the soup
Strain the fish stock through a cloth and season with pepper and salt.
Heat the stock to boiling, then add the minced fish and simmer for five minutes.
In a small bowl, mix the butter and flour together until smooth.
Stir the butter-flour mixture and minced parsley into the soup.
Thicken and serve
In another vessel, combine the hot milk with the dry bread crumbs and baking soda.
Mix the milk mixture into the soup, stirring well, and simmer for one minute.
Serve hot with sliced lemon and crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish stock
- Forms the liquid base of the soup and carries the flavor of the fish.
- Cooked fish
- Provides the main body and flavor of the bisque as it simmers in the stock.
- Butter and flour
- Mixed together to form a roux that thickens the soup and adds richness.
- Milk
- Adds creaminess and softness, mellowing the savory fish flavor.
- Dry bread crumbs
- Absorb liquid and help thicken the soup further, giving it body.
- Baking soda
- Raises the pH slightly, which helps the bread crumbs and milk blend smoothly into the soup.
The step that matters
Mixing the milk and bread crumb mixture into the soup. Stirring well while adding the milk mixture keeps it from clumping or curdling. Simmering only briefly afterward avoids over-thickening or breaking the soup.
