Why it works: Flour and sweet potato work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 627 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Ham Casserole
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Soak the ham slice in milk for 1 hour.
Place the ham in a casserole and pour milk over it.
Bake and finish
Cover and bake in a 300°F (150°C) oven for 1 hour, trimming off excess fat.
Twenty minutes before it is done, spread jelly over the ham.
Add more milk to create gravy, uncover, and let it brown slowly.
Thicken the gravy with flour and garnish with candied sweet potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Provides the main meat, and its fat flavours the gravy as it cooks.
- Milk
- Supplies moisture and forms the base of the gravy.
- Jelly
- Its sugars caramelise and darken the surface of the ham.
- Flour
- Thickens the liquid into a gravy as it heats.
The step that matters
Spreading the jelly 20 minutes before the end. Jelly is mostly sugar, which darkens quickly in oven heat. Adding it too early lets it scorch before the ham is done, while adding it near the end gives an even glaze that browns slowly without burning.
Swap the sweet potato
How well each one fits the dish's main ingredients (ham, milk, flour):
- Arrowrootfits better
- Shallotfits better
- Potatofits better
- Sweet potatothe original
Fit is the average pairing score against ham, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
