First make sure your quinoa is cooked al dente according to package directions and cooled. Then proceed with the recipe.
In a large mixing bowl, sift together flour, baking powder, salt and sugar. Make a well in the center of the dry ingredients.
Measure the milk into a measuring cup. Add the milk, vinegar, water, oil and vanilla to the well in the dry ingredients. Stir with a fork until a thick, lumpy batter forms. That should take about a minute. It doesn’t need to be smooth, just make sure you get all the ingredients incorporated. Fold in the quinoa.
Preheat the pan over medium-low heat and let the batter rest for 10 minutes.
Lightly coat the pan in oil. Add 1/3 cup of batter for each pancake, and cook for about 4 minutes, until puffy. Flip the pancakes, adding a new coat of oil to the pan, and cook for another 3 minutes or so. Pancake should be puffed up, and golden brown.
Rest pancakes on a large plate loosely covered with tin foil until ready to serve with lots of maple syrup and butter! To reheat, place pancakes in on a baking sheet covered with tin foil in a 300 F degree oven for 5 minutes or so.
