What each ingredient does
- Salt
- Draws out moisture and slows spoilage by microbes, which is the basis of the preservation.
- Sugar
- Softens the sharpness of the salt and adds a mild sweetness to the finished butter.
- Saltpetre
- Acts as a curing agent that helps inhibit spoilage bacteria during storage.
- Butter
- The fat being preserved, which carries the salt and sugar flavour through the whole batch.
The step that matters
Working the mixture well into the butter. Salt and cure that stay in pockets will leave some areas under-preserved and others overly salty. An even distribution keeps the whole batch stable and consistently flavoured.
