Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main body and flavor of the croquettes.
- Eggs
- Bind the mixture together and help the coating adhere.
- Soda crackers
- Absorb moisture and add bulk so the mixture holds its shape.
- Melted butter
- Adds richness and moisture to the mixture.
- Milk
- Adds moisture so the mixture forms a soft paste.
The step that matters
Fry in hot lard until golden brown. If the lard is not hot enough, croquettes absorb excess fat and turn greasy and pale, while a properly hot pan browns the coating quickly and seals it, keeping the inside moist.
“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.
