Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Absorbs liquid and gives the filling its crumbly, bound body.
- Beef suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Heart and lights
- Form the main minced body of the filling, giving it its meaty texture.
- Liver
- Adds depth and richness to the filling when grated into the mixture.
- Onions
- Add sweetness and aroma to the minced filling.
The step that matters
Prick the bag occasionally. Steam expands inside the sealed bag as it boils, so pricking releases pressure and prevents the casing from bursting.
Swap the onion
How well each one fits the dish's main ingredients (liver, beef, pepper):
