Why it works: Bread and ham match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 2,536 recipes mention both. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
In a bowl, combine the batter, grated cheese, and made mustard until uniform.
Spread the mixture on slices of bread.
Add slices of ham or meat on top.
Cover with another slice of bread.
Cut into bite-sized pieces.

- Mustardthe original
Fit is the average pairing score against cheese, bread, ham. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
