Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Butter Kept Sweet
Ingredients
Directions
Prepare the butter
Wash all the milk out of the fresh butter and salt it.
Mix the sugar evenly into the butter.
Pack the butter into stone crocks.
Brine and store
Prepare a brine strong enough to float an egg and strain it.
Pour the brine two inches deep over the butter.
Cover the crock tightly.
Serve
When ready to use, cut out the butter without removing the brine.

What each ingredient does
- Fresh butter
- Provides the fat, body and rich flavor that the whole recipe is built on.
- White granulated sugar
- Adds sweetness to the butter.
The step that matters
Prepare a brine strong enough to float an egg. The brine's salt concentration must be high enough to keep the butter covered and help preserve it. A weak brine lets the butter spoil sooner, so test the strength with an egg before pouring.
