Vodka??
Made mashed tonight and they did get hot fast. Hot milk made them even hotter!
But, did they stay hot long enough to get to the table and then melt butter that was placed on them?
That's a great question and no they do not.
But, learned a little trick several years ago from one of my smarter guys.
Mash them ahead of serving. Then place in a stainless mixing bowl with a simmering water bath underneath. Drizzle some hot milk and butter round the edges. Mix in before serving. They actually do stay hot and do not break down. Works great!!
