To Pot Butter
Ingredients
Directions
Prepare
Pack the butter tightly in a cool vessel to exclude air.
Wash the butter with brine to remove milk, then mix in the saltpetre, coarse sea salt, and loaf sugar.
Dry the mixture in an oven, then pound and sift it.
Pack and store
Fill the vessel with the butter, ensuring no air pockets, and soak up any liquid that escapes.
Cover the top with additional salt or brine, secure the lid, and store in a cool place for winter.

What each ingredient does
- Butter
- Forms the fat base that is packed into the vessel to exclude air.
- Saltpetre
- Acts as a curing agent that helps preserve the butter.
- Coarse sea salt
- Draws out moisture and slows microbial growth to help preserve the butter.
- Loaf sugar
- Adds mild sweetness and helps balance the saltiness of the butter.
The step that matters
Packing the butter with no air pockets. Air trapped in the butter allows oxidation and spoilage, which shorten storage life. Packing firmly and removing liquid that escapes helps keep the butter sealed from air.
