Crisp and Tender Almond Flour Pancakes

Directions

1. Separate the eggs. If you have time, warm the yolks and whites by half-submerging the bowls they are in in warm water.
2. Mix the flours and baking powder. Sift into a bowl to break up lumps. Some almond flour may remain in the sifter; break up the lumps with your fingers, then add to the bowl. Whisk in the sugar. Add in the grated peel, if using.
3. If you have the time, use an electric mixer to beat the yolks for 3 minutes until pale and aerated. The pancakes will still be delicious if you decide to skip this step.
4. Whisk together the yolks, milk, and butter. Add the vanilla.
5. Make a well in the dry ingredients, then add the wet ingredients (except the whites). Whisk to combine.
6. Add the salt to the whites. In a clean bowl with clean beaters, beat the whites with the salt until barely-stiff peaks form. They should be moist, not dry.
7. Empty the whites into the bowl with the batter and fold in lightly with a wide rubber scraper until thoroughly combined.
8. Heat a frypan over low to medium heat and add safflower oil or butter (or a mixture of both) to coat the bottom lightly (drain out excess if using oil). Test by sprinkling a few drops of cold water onto the pan; when the water sizzles on the surface, the pan is hot enough.
9. With the tip of a large spoon, drop batter onto surface of oil to form cakes (do not crowd pan). Fry on first side, monitoring the heat level to avoid burning, until tops start to appear dry and bubbles start to burst, leaving air tunnels. Flip to cook the second side briefly. (You can keep them warm for serving by emptying them onto a Pyrex pie plate, covering with foil, and keeping in a 150º F to 200º F oven until ready to serve.)
10. Warm the maple syrup and blueberries together in a heavy saucepan until blueberries are tender and cooked through, then pour into a serving pitcher.
11. Serve the pancakes hot, accompanied by butter and/or warm maple or maple-blueberry syrup.
