Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat and rich fat that bastes and flavours the dish.
- Fat pork
- Adds fat and moisture to the stuffing, keeping it juicy as it cooks.
- Rolled crackers
- Absorb the milk and bind the stuffing so it holds together.
- Egg
- Binds the stuffing ingredients together as it sets with heat.
- Milk
- Moistens the crackers and stuffing, adding softness to the filling.
The step that matters
Baste the duck often while roasting. Duck skin and fat render slowly, and frequent basting keeps the surface moist and helps it brown evenly rather than drying out.
Swap the onion
How well each one fits the dish's main ingredients (pork, egg, milk, sage, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against pork, egg, milk, sage, pepper. Candidates are from the same food group and used in at least 100 recipes.
