Why it works: Onion and thyme are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 11,171 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Household Black-puddings
Ingredients
Directions
Mix the warm blood with ¼ cup of vinegar gradually while stirring.
Add a few blades of thyme to the blood mixture.
If using fresh guts, cleanse and soak them in a basin with a handful of coarse sea salt for 2 hours; if dry, soften in cold water.
Cut onions into quarters and boil in salted water for 7-8 minutes, then drain.
Cut the pork fat into small dice and warm in a stewpan with the onions for 20 minutes, then remove from heat.
Pass the blood through a sieve into a stewpan and warm it on low heat while stirring continuously.
When the blood is tepid, mix in the onion and pork fat, season, and add a little rum.
