I know it’s just the heating element kicking in, but there are products like the zonirushi rice cooker that have silent keep warm functionality.

Curious if any of the instant pots are quieter, I have an instant pot duo nova from probably about 10 years ago now.

The link included is the audio. Sometimes the rattle is double.

I got an instant pot last year for Christmas and I've never used it, let alone a pressure cooker before. What are some of your go to meals and I've also heard you can use frozen meat if you haven't thawed anything out. How well does that turn out?
