My dad recently bought an induction burner. From what he's told me, I get the feeling he's not using the right pots/pans on it because it can take up to 10 minutes to boil water. I've never used an induction burner myself, but my understanding is they should be much more efficient than this. Can anyone reccomend some good cookware for use on an induction burner I could get him for xmas? Ideally, I'd like a pot large enough for cooking pasta and a frying pan.
