Tbh, working in food I'd rather the nitrates are in and I just give them to him occasionally. Nitrates are really handy for preventing botulism!
I might give it a go, as you said, I wasn't intending on cutting them into discs. I gave my son strips of chicken tikka yesterday (mild, home made version) and he was fine with them so perhaps he's better at chewing (and spices) than I thought.
I think there is a suggestion you should save cured meats until after the age of 1 as some are uncooked and many are high in salt but I was thinking of cooking them anyway.
