Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main bulk and meaty texture of the filling.
- Liver
- Adds a rich, savoury depth of flavour to the filling.
- Suet
- Adds fat that keeps the filling moist and tender as it cooks.
- Dried meal
- Absorbs liquid and helps bind the mixture together.
- Gravy
- Adds moisture and savoury flavour throughout the filling.
- Onions
- Contribute sweetness and aroma as they soften during cooking.
The step that matters
Dab the bag with a pin before boiling. Air and steam trapped inside expand as the haggis heats. Without small vents, pressure can build and split the bag during the long boil.
