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 ↓
Boiled Ham
Ingredients
Directions
Prepare the ham
Soak the ham in a mixture of vinegar and water for a few hours.
Place the ham in a pot with cold water.
Cook
Bring to a boil, then add the celery, turnips, onions, and herbs.
Simmer gently for about 4 hours or until tender.
Finish and serve
Remove the ham, strip off the skin, and cover with bread crumbs.
Garnish with a paper frill around the knuckle and parsley or vegetable flowers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Is the main protein, becoming tender and flavorful as it simmers slowly in liquid.
- Vinegar
- Its acidity in the soaking liquid helps season and lightly firm the surface of the ham.
- Celery
- Adds aromatic flavor to the cooking liquid as it simmers with the ham.
- Turnips
- Add mild sweetness and earthy flavor to the cooking liquid and the finished dish.
- Onions
- Contribute savory sweetness and aroma to the simmering liquid.
- Bread crumbs
- Form a coating on the skinned ham that adds texture to the surface.
The step that matters
Simmer gently for about 4 hours or until tender. A rolling boil toughens the meat and can break the surface apart. Gentle simmering lets the connective tissue slowly soften, so the ham becomes tender and stays intact.
