Ruger5 : lol I have granite too and am aware of the risks associated. You are taking on extra risk of contamination when you prepare raw meat directly on the countertop. Regarding coldstone, the granite part doesn't influence the taste of the icecream beyond someone believing that it taste different because it was prepared differently.
@Lateralus : I am WELL aware of risk. We take risks with food contaminates every single day. While I can not vouch for the cleanliness of commercial food preppers or yours or anyone elses - I can most definitely vouch for the cleanliness of my kitchen - I'm 100% A OK with this - if you are not, you should not. ðŸ‘
