1 cup blue cornmeal
You can use regular yellow cornmeal if that's all you've got.
1/2 cup oil
Any vegetable oil will do. I used my favorite not-too-olivey baking olive oil - Jovia Groves' 2007 Arbequina, but any olive oil will do. You can order Jovia from Extra Virgin.
1 tsp vanilla extract
I used 1/2 t vanilla extract and 1/2 t orange extract to give the pancakes an orange flavor. I highly recommend it! If you don't have orange extract, you could use some orange zest instead.
More, for greasing griddle, I prefer to use butter to grease, but either would work.
