What each ingredient does
- Coarse sea salt
- Draws out moisture and inhibits spoilage bacteria, preserving the butter and seasoning it.
- Brown sugar
- Adds mild sweetness and a little moisture that balances the saltiness.
- Saltpetre
- Acts as a curing agent that helps preserve the butter during storage.
- Butter
- Provides the fat that the cure is worked into, carrying its flavour through the whole block.
The step that matters
Working the mixture into the butter thoroughly. Salt and cure only preserve where they touch. If the mixture is unevenly distributed, some areas stay under-cured and spoil sooner, while others taste too salty.
