Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Absorbs liquid and fat, giving the haggis its crumbly, filling body.
- Beef suet
- Adds fat that keeps the filling moist and rich during boiling.
- Liver
- Contributes savoury depth and body to the filling.
- Onions
- Add sweetness and moisture to the filling as they cook.
The step that matters
Fill the stomach moderately. Oatmeal and other fillings swell as they cook, and an overfilled stomach can burst. Leaving room lets the contents expand safely while boiling.
Swap the onion
