I’m really sorry about your dog. It can be a major bereavement, and I think you should forgive yourself for making an impulse buy!
I bought one of these in a sale on Amazon, to replace my pressure cooker, on the advice of a very sensible friend who used hers a lot. I promptly lost the instructions, and I can’t get on with it at all. I tried pressure cooking meat for a stew, and it burnt. It sits in my kitchen, reproaching me.
To be fair to myself, I’ve had a lot of health issues in the last year, and I have constant brain fog. I’ve made a resolution not to make any more impulse buys!
Do be kind to yourself, though xxx
