Instant Pot or another cooker?

Do you mean the pressure cooker function? That’s the main benefit of an Instant Pot, I believe. But pressure cooking isn’t going to make much of a difference for rice, or for most other lentils I guess.

I bought my Instant Pot in Canada a couple of years ago and brought it back here. I’ve never seen that brand here, but I think Costco often sells multi-cookers.

EDIT: See (and perhaps merge with?) this thread:
