Why it works: Vinegar and onion are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 18,226 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Smothered Ham
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the ham
Soak the ham.
Scrub the ham.
Trim the blackened underside of the ham until the meat is clean and red.
Wash the ham with vinegar.
Rub the ham in vinegar well.
Cover the underside with a paste of flour and water.
Lay the ham upside down in a roaster.
Braise the ham
Pour 2 cups of cold water around the ham.
Pour 2 tablespoons of vinegar around the ham.
Stir in 1 tablespoon of sugar.
Stir in 1 tablespoon of minced onion.
Cover the ham closely.
Bake the ham in a 350°F oven for 25 minutes per pound.
Baste the ham five times.
Finish and serve
Remove the paste while hot.
Sift fine cracker crumbs over the top.
Brown the ham in a 400°F oven.
Serve the ham cold for best flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Is the main cut that is cleaned, braised and browned to serve.
- Flour
- Forms a paste that shields the underside of the ham during baking.
- Vinegar
- Adds acidity that brightens the flavor and helps tenderize the surface.
- Cracker crumbs
- Form a crisp, browned crust on top of the ham.
The step that matters
Remove the paste while hot.. Paste that cools hardens and sticks to the meat, so it must be lifted off while still warm to come away cleanly without tearing the surface.
Swap the onion
How well each one fits the dish's main ingredients (ham, vinegar, flour, sugar):
- Mustardfits better
- Shallotfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against ham, vinegar, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
