Why it works: Butter and milk 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 ↓
Baked Ham and Potatoes
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.
Assemble
Place the ham in a small buttered baking dish.
Mix the sliced potatoes with flour, salt, and paprika.
Spread the potato mixture on top of the ham.
Dot the top with small bits of butter.
Pour the milk over the dish.
Bake
Bake in a moderate oven at 350°F (175°C) for 1½ hours.
Remove the cover for the last 15 minutes to brown the potatoes.

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
- Sliced ham
- Forms the base layer and supplies savory, salty meat flavor.
- Potatoes
- Form the starchy top layer that softens during baking and browns at the surface.
- Milk
- Provides liquid that cooks the potatoes gently and forms a creamy sauce.
- Butter
- Adds richness and helps the top layer brown during baking.
- Flour
- Lightly thickens the milk so the sauce becomes creamy rather than watery.
The step that matters
Remove the cover for the last 15 minutes. Uncovering lets surface moisture escape and heat reach the potatoes directly, so they brown instead of staying pale and steamed.
Swap the potato
How well each one fits the dish's main ingredients (ham, butter, milk, flour):

- Asparagusfits about as well
Fit is the average pairing score against ham, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
