Why it works: Flour and rye match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,320 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Cold Ham
Ingredients
Directions
Make the sauce
Melt the currant jelly, butter, and pepper in a saucepan.
Add thin slices of ham and let it boil for 1 minute.
For a brown sauce, boil ham scraps in a stewpan with a little water.
Strain the liquid and add thick cream.
Thicken with browned flour rubbed smooth with butter.
Finish and serve
Boil slices of ham in this sauce and serve with browned potatoes or potato cakes and toasted rye bread.

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
- Currant jelly
- Adds sweetness and a fruity tang that balances the salty ham.
- Thick cream
- Adds richness and body, softening the sauce's flavour and texture.
- Browned flour
- Thickens the sauce so it coats the ham slices.
- Ham
- Provides the savoury meat flavour that the sauce carries.
The step that matters
Thicken with browned flour rubbed smooth with butter. Flour added directly to hot liquid forms lumps. Rubbing it smooth with butter first lets it disperse evenly, so the sauce thickens without clumps.
Swap the currant
How well each one fits the dish's main ingredients (butter, pepper, ham, cream, flour, potato, rye):
- Lemonfits better
- Figfits better
- Cherryfits better
- Currantthe original
Fit is the average pairing score against butter, pepper, ham, cream, flour, potato, rye. Candidates are from the same food group and used in at least 100 recipes.
