I think this is what I came here to say, too! Bags of MSG are soooo cheap, I have a tiny jar of it next to my oven and it’s so satisfying and so much fun to taste what you’re cooking before and after adding a sprinkle of MSG. Amazing difference!
I’ve learnt to add umami in lots of other ways, but for some recipes, msg really is a good hit.
Our stovetop is having issues and I’d had a similar thought, so I’m hanging out to hear people’s reckons on this too!
