You buy in mashed potatoes? Really?
Look, even my kids will tell you that I am a lousy cook.
But mashed potatoes?
Take some potatoes. Don’t bother to peel them or anything. Washing is optional - you are going to boil the suckers anyway.
Do get rid of the green bits. They will give you the trots.
Throw them in a pot.
Put a fire under it.
When they get mushy, hit them with a hammar, a K-Bar, a tanker bar, whatever is handy. We have an old tire iron for the chore.
Toss in butter,garlic, and cream.
Serve hot.
*snicker* ...lumpy potatoes, its what fer dinner.
