Notes
My potatoes were large - 14-16 oz each and I wanted them to be pretty tender so I went with a max time of 18 minutes. For a slightly firmer texture I would have gone with 16 minutes.Most potatoes area little smaller, more like 12 -14 oz so I would go with 14-16 minutes.And for a more average size potato like you might get in a 5 pound bag (this are usually more like 8-12 oz each) I would go with 12-14 minutes.Anything smaller of if you really prefer a firmer texture, I'd go with 10-12 minutes.
