Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Scotch Haggis
Ingredients
Directions
Prepare the organs
Wash the sheep's pluck.
Place it in a pot to boil, allowing the windpipe to hang out to release impurities.
Boil gently for 1.5 to 2 hours.
Have the butcher clean the sheep's stomach.
Wash it thoroughly.
Boil it in cold water until it contracts.
Remove the stomach.
Wash it again.
Soak it in saltwater until needed.
Make the filling
Mince the lungs and heart, discarding gristly parts.
Grate the liver.
Combine the liver with the minced organs in a large bowl.
Toast the oatmeal.
Add the toasted oatmeal to the bowl.
Finely chop the suet.
Add the suet along with the onion, salt, pepper, and 1 cup of the boiling liquid, then mix well.
Stuff and cook
Fill the stomach with the mixture, leaving some space.
Sew the stomach closed.
Boil gently in water for 3 hours.
Prick the haggis several times to prevent bursting.
Place a plate under it to avoid sticking.

What each ingredient does
- Oatmeal
- Absorbs liquid and gives the filling its crumbly, firm texture.
- Suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Sheep's stomach
- Acts as the casing that holds the filling together while it boils.
- Sheep's pluck
- Provides the main meaty body and savoury flavour of the filling.
- Onion
- Adds aromatic sweetness and depth to the filling.
- Cooking liquid from the pluck
- Supplies moisture that hydrates the oatmeal and keeps the mixture loose.
The step that matters
Prick the haggis several times. As the filling heats, steam and expanding air build up inside the sealed stomach. Pricking lets the pressure escape gradually, so the casing does not burst during boiling.
