Butter, to Preserve
Ingredients
Directions
Clean the butter
Work every particle of water out of the butter using a wooden spatula.
Mix in a few washed and dried black peppercorns.
Store
Place the butter in a jar and cover the top with moist sugar in a bag or between two folds of linen.
Alternatively, clean the butter well and mix in a small amount of salt.
Put the butter into a porous vessel and keep it cool with a wet cloth or in a cooling machine.
Clarify
Melt the butter at a low temperature, skim and strain it, then let it cool completely to separate the water.

What each ingredient does
- Butter
- Provides the fat that is preserved and carries the flavor of the finished dish.
- Black peppercorns
- Adds a sharp, aromatic flavor to the butter.
- Moist sugar
- Draws moisture from the surface and adds a little sweetness.
The step that matters
Remove every particle of water from the butter. Water left in butter allows bacteria and mold to grow and spoil it, so the butter must be as dry as possible before preserving.
