Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Salmon Souffle
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
Make a thick white sauce by melting butter, adding flour, and gradually whisking in milk until smooth.
Stir in cracker crumbs, onion juice, parsley, Worcestershire sauce, ketchup, and salmon.
Heat the mixture thoroughly.
Bake and serve
Add the beaten yolks of the eggs to the mixture.
Fold in the beaten egg whites gently.
Pour into a casserole or ramekins and bake at 350°F (175°C) for 25 minutes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Whites trap air for lift, and yolks enrich the custard-like base for a soft, set texture.
- All-purpose flour
- Thickens the butter and milk into a white sauce that holds the mixture together.
- Milk
- Forms the liquid base of the white sauce, adding moisture and body.
- Salmon
- Provides the main flavor and protein that gives the souffle its body.
- Rolled cracker crumbs
- Absorb liquid and add bulk, helping the mixture hold its shape.
The step that matters
Fold in the beaten egg whites gently. Egg whites hold air bubbles that make the souffle rise. Stirring or deflating them harshly knocks out that air, so the souffle bakes flat and dense.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, milk, onion, sauce, ketchup, salmon):
- Capersfits better
- Garlicfits about as well
- Nutmegfits about as well
- Parsleythe original
Fit is the average pairing score against butter, flour, milk, onion, sauce, ketchup, salmon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
