Blend all of the ingredients in a blender, making sure to scrape the sides if need be so that the batter is smooth and not clumpy.
Heat skillet on med-low heat.
Put a dollop of butter or palm shortening in the skillet to prevent sticking. This is important. Do this before cooking each tortilla.
Scoop about 1/4 cup of the batter onto the skillet and smooth it out quickly with a rubber spatula. It will begin cooking and thickening right away, but the batter is pretty forgiving and will let you continue to smooth it out for a bit.
Let the batter cook on the first side for 2-3 minutes before flipping, then cook on the second side for another 2-3 minutes.
Repeat steps with remaining batter.
