What each ingredient does
- Common salt
- Preserves the butter by drawing out moisture and slowing spoilage.
- Loaf sugar
- Adds a mild sweetness that balances the saltiness of the cure.
- Saltpetre
- Acts as a curing agent that helps inhibit spoilage in the butter.
- Butter
- Forms the base that the salt mixture preserves and seasons.
The step that matters
Layering the salt mixture through the butter. Salt must be distributed evenly between layers so every part of the butter is protected; uneven salting leaves spots that spoil more quickly.
