Tips for making slow cooker mashed potatoes:
Why dirty a strainer! Wearing oven mitts, hold the slow cooker insert with the lid opened a crack and pour the water down the sink drain.
Take care to not over mix the potatoes; they will become gluey in taste and texture.
Be careful not to scrape the beaters against the ceramic slow cooker insert as much as possible.
