Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Pigs' Feet Pickled
Ingredients
Directions
Cook the feet
Scrape and wash the pigs' feet clean.
Place them in a saucepan and cover with hot water.
When partly cooked, add salt.
Boil for 4 to 5 hours until soft.
Pickle
Pack the feet in a stone crock and pour hot spiced vinegar over them.
Let them sit for 1 to 2 days before using.
Fry and serve
For breakfast, split the feet.
Make a batter with eggs, milk, salt, butter, and enough flour to thicken.
Dip each piece in the batter and fry in hot lard.
Alternatively, dip in beaten egg and flour and fry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs' feet
- Provide the main meat, which becomes tender through long boiling.
- Spiced vinegar
- Acidity that preserves and flavours the feet during pickling.
- Eggs
- Bind and thicken the batter so it coats each piece.
- Flour
- Thickens the batter and helps it cling to the fried pieces.
- Milk
- Moistens the batter so it spreads evenly and stays tender.
- Lard
- Fat for frying that browns the batter and crisps its surface.
The step that matters
Boil for 4 to 5 hours until soft. Collagen-rich connective tissue only turns tender after prolonged simmering. Stopping early leaves the feet tough and hard to split or pickle well.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
