How to make mashed potatoes right, do not boil the taste away.
I only use my PC to cook potatoes, then I only add butter and can milk, S&P to whip in my mixer.
You can also use sour cream instead of can milk.
They are very good. If any are left over, I form a patty, dip in flour and fry them for potato patties.
If you want to freeze mashed potatoes, never add milk!
Use butter,S&P, and sour cream, they are very good and not run all over your plate when thawed.
I freeze in portions, so I can only take out what will be eaten.
