Mix all ingredients.
Let rest for 6 to 8 hours to ferment.
(Cover bowl and leave on counter.)
Using a small non-stick frying pan, ladle about ¼ cup of batter into the pan, and thinly spread.
Bubbles will form immediately.
Do not turn until the cake has dried out a little.
Loosen gently and turn to cook on other side.
The first side takes about 1½ minutes, the other side about 1 minute at medium temperature.
Serve with a bean mixture spooned over them, or use like a crepe.
