Both polenta and grits are made from stone ground corn. The variety of corn distinguishes whether it’s Polenta or Grits. Polenta is made from yellow corn and grits from white corn (or hominy). Some say it’s more about the region – Italy or the Southern States, rather than the taste.
Cornmeal is the main ingredient; Polenta or Grits is the name of the dish.
Polenta is Italy’s response to our mashed potatoes. The creamy base for so many things.
Grits are coarser and white. Both taste very similar until additions are made.
