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
Prepare the feet
Scrape and wash the pigs' feet clean.
Place them in a saucepan and cover with hot (not boiling) water.
When partly cooked, add coarse sea 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 2 eggs, ½ cup milk, 1 teaspoon butter, and enough flour to create a thick batter.
Dip each piece in the batter and fry in hot lard.
Alternatively, dip them in beaten egg and flour, then fry.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs' feet
- Provide the meat and gelatin that give the dish its body and texture after long simmering.
- Spiced vinegar
- Acidity that pickles the feet, flavouring and preserving them during the resting period.
- Eggs
- Bind the batter and help it set and brown when fried.
- Flour
- Thickens the batter so it coats each piece and crisps when fried.
- Lard
- Fat for frying that browns the coating and adds richness.
The step that matters
Boil for 4 to 5 hours until soft. Long, gentle cooking breaks down collagen in the connective tissue into gelatin, making the feet tender. Stopping early leaves them tough and hard to pickle evenly.
“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.
