Butter Kept Sweet

Ingredients

Directions

Prepare the butter

  1. Ensure the butter is fresh and has all the milk washed out.

  2. Mix the sugar evenly into the butter.

Pack and brine

  1. Pack the butter into stone crocks.

  2. Make a brine strong enough to float an egg, then strain it.

  3. Pour the brine two inches deep over the butter.

  4. Cover the crock tightly.

Serve

  1. When ready to use, cut out the butter without removing the brine.

What each ingredient does

Butter
Forms the body of the dish and carries the flavor that the brine and sugar affect.
White granulated sugar
Adds a mild sweetness that balances the salty brine.
Coarse sea salt
Makes the brine that covers and seasons the butter.

The step that matters

Make the brine strong enough to float an egg. The salt concentration decides how well the brine protects the butter, and a floating egg shows the brine is salty enough. The butter must stay fully under the brine so air cannot reach it and spoil it.
