Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shredded salmon
- Forms the main body of the dish and provides its protein and flavour.
- Milk
- Forms the liquid base of the sauce that moistens the layers.
- Flour
- Thickens the milk into a smooth sauce as it cooks.
- Egg
- Sets when heated, helping bind the sauce and give it body.
- Cracker crumbs
- Add bulk and absorb moisture between the salmon layers.
The step that matters
Stir the egg in off the heat. Egg proteins set at around 160°F and scramble if added to a boiling sauce. Removing the pan from heat first lets the egg thicken the sauce gently and evenly.
