The BEST cornbread recipe I have every made is the one below and I have tried LOADS. This even beats out Pioneer Woman's recipe which I found to greasy.
Classic Corn Bread
1 cup cornmeal (5 oz/155 g)
1 cup plain flour (5 oz/155g)
1 1/2 tsp baking powder
1/2 tsp baking soda / bicarb
1/2 tsp salt
1 1/3 cup (11 fl oz / 340 ml) buttermilk
3 Tbsp unsalted butter, melted or canola or olive oil [I've tried oil and prefer the melted butter, bacon grease would rock, though!]
2 large eggs
Whisk the eggs, add the honey (if using), buttermilk and butter and whisk until blended. Mix the other ingredients together and stir into the wet ingredients.
Butter an 8 inch cast iron skillet and pour mixture in, bake at 220C for 20 - 25 mins or until a toothpick comes out clean.
