Why This Recipe Works

Many buttermilk mashed potatoes recipes remove so much butter that the potatoes taste lean and lack creaminess, and suffer from curdling because of a simple substitution of buttermilk for cream.

Then we determined that we could prevent curdling by adding the melted butter to room-temperature buttermilk, coating the proteins in the buttermilk and thus protecting them from heat shock when added to the hot potatoes.
