To Preserve Butter
Ingredients
Directions
Cure the butter
Mix the salt, sugar, and saltpetre together thoroughly.
For every 16 ounces of cleansed butter, add 1 ounce of the salt mixture.
Work the mixture into the butter until well combined.
Pack and store
Pack the butter into pots, ensuring they are airtight.
Store the pots in a cool place for at least one month before use.

What each ingredient does
- Butter
- Forms the fatty base that the salt cure is worked into and preserved.
- Coarse sea salt
- Draws out moisture and inhibits microbial growth, which preserves the butter.
- Loaf sugar
- Adds mild sweetness that balances the saltiness of the cured butter.
The step that matters
Pack the butter into pots, ensuring they are airtight.. Air exposure allows surface spoilage and oxidation to start. Packing without gaps keeps the butter sealed from air and microbes, so the salt cure can preserve it throughout during storage.
