Why it works: Beef and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and 17,091 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Directions
Hang the rump of beef for 5 to 6 days.
Bone and lard the beef thickly with bacon or ham pieces, ensuring they do not show on the surface.
Mix the minced onion, parsley, thyme, garlic, pepper, and salt to season the beef.
Add any leftover seasoning to the vinegar, port wine, and salad oil; steep the beef in this mixture overnight.
The next day, wrap the beef in paper and roast it on a spit.
Baste the beef well while roasting.
Serve with thick brown gravy, lemon juice, and sliced pickled cucumbers.
Garnish with slices of boiled carrot and scraped horseradish.
