  • Hello Flo, I was thinking about getting a stove top pressure cooker, but my friends keep talking about Instant Pot. I found your blog and think I’ll get one. But do you recommend the Smart or the 7 in 1?

    • Hi Ingrid. You’re friends are right! I learned on a stove top one many years ago and they freaked me out which is why I had never used one since. The Instant Pot has a lot of safety features built in that make it easy and safe to use. I prefer my Smart to the DUO, they are both 7 in 1. The Smart allows me to record my recipes in the app, so I don’t have to remember or manually plug in the right time/pressure. I also like not having to calculate the delayed time to cook, I just plug in what time I want it to start. But mostly, I love my Smart, so that I can sous vide. Only the Smart allows for temperature control. Hope that’s helpful.

      • Thank you so much Flo! That was SUPER helpful!! I didn’t know if I would sous vide often. And if need be, I could always borrow my brother’s. But not having to calculate a delayed cooking time and not having to remember the right time and pressure is ideal. I have the worst memory! And bad at math some times… =) Thank you for your advice!

    • I learned on one in high school many years ago. I also have a friend who used to use one and have, on multiple occasions, had to clean food off her ceiling. She is the one who introduced me to the Instant Pot. 😉
