  1. I know you don’t *have* to soak your lentils, but I’ve been brainwashed into thinking that you should if you can. Any estimates on how much to adjust the InstantPot cooking time with an overnight soak? Thanks!

  2. I’d like to try this recipe, it sounds and looks so good. My question is can I substitute white/cream color lentils? Thanks in advance.
