Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Acts as an emulsifier, helping the butter and oil bind smoothly with the ham.
- Melted butter
- Adds richness and a smooth, spreadable texture once it cools and firms.
- Salad oil
- Keeps the mixture moist and softer by adding liquid fat.
- Ground mustard
- Adds sharp, pungent flavor that cuts through the richness of the ham and fat.
The step that matters
Mix the ham with the fats and yolk. The beaten egg yolk must be well combined with the melted butter and oil so the fat emulsifies evenly. If the fat is too hot or added too fast, the mixture can separate and turn greasy rather than smooth and spreadable.
Swap the mustard
