Separate egg whites ahead of time into a glass container. Cover with plastic wrap, pierce the wrap with a fork to make a few small holes, and refrigerate. Take egg whites out of the fridge and remove the plastic wrap, 6-8 hours before you make your macaron shells.
Preheat oven to 325°F (165°C).
Combine dry ingredients in a food processor to get a finer texture. Combine egg whites, food color and vanilla.
Fit a mixer with the wire whip attachment and fold the whipped egg whites and vanilla with the dry ingredients. Pour in your egg whites, and add a pinch of salt.
Fill your piping bag with batter. Smack the pan on the counter 3 times on each side of the pan to smooth out peaks and eliminate trapped air bubbles. Let sit for 15 minutes.
Bake for 12-14 minutes, turning the pan halfway through. Let cool completely.
To assemble macarons, spread 1-2 teaspoons of jam between the cookies.
