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 ↓

Ingredients
Directions
Prepare the bag
Wash the sheep's bag in cold water, scrape, and clean it well. Soak it overnight in cold water with salt.
Make the filling
Wash the pluck and place it in a pot of boiling water with 1 tablespoon of salt. Boil for 2 hours, letting the windpipe hang out of the pot.
Once cooled, cut off the windpipe. Grate half the liver and mince the heart, liver, suet, and onions very small.
Add the toasted oatmeal, pepper, salt, herbs, and 1 cup of the reserved liquor to the mixture. Mix well.
Fill and boil
Fill the bag slightly more than half with the mixture and sew it up.
Place the bag in a pot of boiling water and boil for 3 hours, pricking it occasionally to prevent bursting.

What each ingredient does
- Oatmeal
- Absorbs the liquor and fat, giving the filling its crumbly, bound texture.
- Suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Onions
- Add sweetness and savoury aroma to the filling.
- Reserved liquor
- Provides moisture that softens the oatmeal and keeps the filling tender.
The step that matters
Pricking the bag during boiling. Steam builds up inside the sealed bag as it cooks, and occasional pricking releases pressure so the bag does not burst.
