Add to skillet the 3Tbs oil and put into oven.
Add to bowl the 2 cups corn meal mix, eggs, and milk and whisk together until looks like pancake batter or cake batter. Don't over mix. Then carefully remove the iron skillet from oven(caution-very hot oil), pour oil into bowl of the mix. Whisk oil 4-5 rounds of the bowl, does NOT have to be completely incorporated, then pour into iron skillet. (Will sizzle because skillet should be very hot when you pour the batter in.)Put into the hot oven for 18-23 minutes.
