Grits are one of those things you either love or hate. They taste like polenta, to me. Kinda of creamy, with a faint corn taste.
I cook them 4 parts liquid to one part grits, simmer for at least 5 minutes, as long as you have time for. I like to use half water/half milk, but even just water tastes fine.
Season to taste with salt, pepper, butter. We like cheddar cheese in ours.
