Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Dr. Ratcliff's Pork Jelly
Ingredients
Directions
Make the stock
Beat the leg of pork.
Break the bone of the pork leg.
Place the pork leg in a pot with 3 gallons of water.
Simmer the pork until the liquid is reduced to 1 gallon.
Add ½ ounce mace and ½ ounce nutmeg to the pot.
Strain the liquid through a fine sieve.
When the liquid is cold, remove the fat.
Make the jelly
Boil the lambs' feet in water for 10 minutes to remove the leg bone.
Combine the lambs' feet with 1 pint of water mixed with flour and salt in a stewpan.
Cook over heat, stirring frequently until boiling.
Add the onion, celery, parsley, and parsnip to the stew.
Boil gently for 2 hours.
Serve
Serve one coffee cupful at the beginning and end of the day, adding salt to taste.
Serve plain or with melted butter and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork leg
- Its meat and bone release body and savoury flavour into the stock.
- Lambs' feet
- Their collagen turns to gelatin, helping the liquid set firm when cold.
- Flour
- Thickens the liquid as it heats and comes to a boil.
- Mace
- Adds warm, aromatic spice flavour to the stock.
- Nutmeg
- Adds warm, sweet aroma to the stock.
- Onion
- Softens during gentle boiling and adds savoury aroma to the stew.
The step that matters
Remove the fat when the liquid is cold. Fat floats on the surface and solidifies as the liquid cools, so it can be lifted off in one piece. Leaving it in makes the jelly greasy and cloudy in texture.
Swap the mace
How well each one fits the dish's main ingredients (pork, nutmeg, lamb, flour, onion, celery, parsley):
- Thymefits better
- Marjoramfits better
- Cuminfits better
- Macethe original
