Stir together flours, water, and vinegar in a glass bowl. Set on the counter or in oven with only the light on overnight or for 24 hours at the most. Dough should be bubbly, especially inside.

In a separate bowl, beat the eggs, salt, olive oil, and baking soda. Stir into batter. Batter should be fluffy.

Pour onto buttered griddle set at medium-high heat and flip when bubbles pop and leave holes. Serve with grade B maple syrup, applesauce, or blueberry sauce.
