Preheat oven to 375. Lightly grease an 8x8 baking pan. Assemble your ingredients.
In a large mixing bowl, add Olive Oil, Milk, Lemon Juice and Egg. Whisk to combine.
Add Cornmeal, Sugar, Baking Soda, Cream of Tartar, Kosher Salt and Thyme. Whisk to combine.
Add Flour and fold it in until evenly mixed.
Pour the batter into the prepared pan. Bake at 375 for 25-30 minutes. It is normal for the top to crack. Cornbread is done when a gentle press on the center does not make an indent.
