Very very very much so. Especially since you need milk and butter to make the mashed then more butter to bake them with a delicious crust.
Delicious but I'm still craving baked potato potato salad ( with extra radishes and green onion).
In BC they have no idea that mash and wort are worth big bucks as feed and send this valuable product out to sea through the sewer system.
And they think they are green?
