To Salt Butter
Ingredients
Directions
Prepare the butter
Mix the butter with the coarse sea salt thoroughly.
For a superior mixture, combine the fine dry salt, sugar, and saltpetre for every pound of butter.
Pack the crock
Wash the inside of the crock with strong brine and rub it with salt if using plain salt.
Press the butter into the crock, ensuring each addition is incorporated well.
If not filling the crock at once, smooth the surface, sprinkle with salt, and cover with a cloth to exclude air.
When adding more butter, remove the cloth, scrape off the salt, and incorporate the new butter completely.
Top with salt and seal the crock when full.
Place the mixture in a crock and cover it tightly with a bladder.

What each ingredient does
- Butter
- Forms the bulk of the preserved mass, giving the finished product its fat and texture.
- Coarse sea salt
- Draws out moisture and seasons the butter, helping to preserve it.
- Fine dry salt
- Mixes evenly through the butter, adding seasoning and helping to preserve it.
- Sugar
- Adds a little sweetness that balances the salt's sharpness.
The step that matters
Incorporating each addition of butter. Salt is the main preservative here, so each new layer must be fully mixed with the salt and the surface kept covered to exclude air. Air exposure lets spoilage microbes grow and oxidise the fat.
