No self respecting southern would consider polenta even close to stone ground grits. In southern households grits recipes and techniques are passed down generations. Plus no self respecting southern would ever have quick cook or instant grits in their house. That is quoting from my great, great grandmother, great grandmother, grandmother respectively

How long do you cook stone ground grits and maybe you can share one of your grandmothers recipes.

I use Bob's Red Mill polenta. Get it at Publix. You might have to visit several stores, they don't have it in all of them. Store manager should be able to tell you.

You can buy them at Fresh Market.

Grits are a day long process, my recipes are had written by each generation, for family only. Each has different ingredients and techniques. Our son uses my great grannies, but adds smoked Gouda and parmigiana.

I can’t give you our fried chicken recipe, but I can tell you I have never gotten it right. I fail every time when to turn the chicken. In my head my great granny said you can smell when to turn the chicken, I am alway too early. Chicken should only be turned once. I go out for fried chicken

I’ll have to give the stone ground grits a try.
I understand family recipes, it’s like my mother’s sauce, if I showed you I’d have to make you swim with the fishes…lol

I’m from GA and have always bought freshly ground grits from Logan Turnpike. The grind them then ship them and they are wonderful! Logan Turnpike Mill

The Old Mill store (not the restaurant)in Pigeon Forge, TN has both white and yellow stone ground grits available in their online store (shop.old-mill.com).They are authentic stone-ground. The store is actually in the old historic mill that is still operating.

There is a vendor at the Sat.am Farmer’s Market that sells them.
They were located on the side of the square by Rustic Rose and Five Guys.

Thank you.
