Notes
If you want your potatoes a bit firmer for a chunkier mashed potatoes, I would set the timer for only 4 minutes.Add the milk a little at a time instead of all at once — this helps you control the consistency and avoid potatoes that turn out too thin. (Thank you to our reader Ally for this tip!)
