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 ↓
Ox- Blood Puddings
Ingredients
Directions
Prepare the blood
Let the blood run into a deep pan and stir continuously until nearly cold.
Add salt and rub through a fine sieve.
Mix the milk with the blood in a large bowl.
In another bowl, combine the chopped suet, minced onion, pepper, and oatmeal. Add this mixture to the blood and milk.
Fill the skins
Clean the pudding skins by washing thoroughly and soaking overnight in saltwater.
Tie one end of the skins, turn them inside out, and fill them halfway. Tie them in rings or equal lengths.
Cook and serve
Bring a pot of water to a boil. Add a little cold water to reduce the boil. Gently place the puddings in.
After five minutes, remove the puddings. Prick them with a large needle. Return them to the pot. Boil the puddings for half an hour.
Hang them in a dry, cool place to store.
Place the puddings in hot water for 10-15 minutes. Broil them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Blood
- Coagulates when cooked and forms the firm, dark body of the pudding.
- Suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Oatmeal
- Absorbs liquid and gives the filling body and a softer, crumbly texture.
- Milk
- Thins the blood mixture and adds moisture and mild sweetness.
- Onion
- Adds aroma and savoury flavour to the filling.
The step that matters
Pricking the puddings after the first boil. Cooking traps steam and expanding air inside the skins; pricking lets it escape so the puddings do not burst while they finish cooking.
