When soft peak stage is reached add food coloring and vanilla. Mix till stiff peak stage.
Add about ¼ the dry ingredients to the egg whites. Fold with spatula till combined.
Then add the rest of the dry ingredients and gently macaronage (fold) till “lava” texture is reached. The batter should make ribbons that don’t break when you lift the spatula. Try making a figure 8.
Line 2 cookie sheets with parchment, using a tiny dab of batter on each corner as glue.
Add batter to piping bag using a plain round tip.
Pipe about 1 ½” circles, holding bag perpendicular to cookie sheet. To break off batter, make a little swirl motion on top.
Bang sheet on counter to get rid of bubbles and to help tops get smooth.

Preheat oven to 300 degrees F.

FILLING
Bring 1-2 inches water to a boil in a medium saucepan for a bain marie. Place a bowl over pan. Water should be just below bottom of bowl.
Add egg whites and sugar to bowl. Heat until mixture reaches 160 degrees F.
Pour hot egg whites into a mixer bowl with the whisk equipped, beat until stiff peaks and room temperature.
Cut butter into tbsp size chunks. Mix in one by one. Keep mixing until smooth and glossy, may look worse before it gets better. If your icing is too warm put in fridge for 10-20 minutes.
Beat in vanilla and strawberry powder. (Powder is made by crushing freeze dried strawberries in a baggie. Sifted to remove hard chunks.)
Spoon frosting into a icing bag with desired tip or cut a 1/4" tip off.
Let shells dry completely before piping in filling. Make little macaron sandwiches by matching up with same sized tops and bottoms.
Pipe a wall of icing leaving a hole in the middle. Spoon a dollop of jam in center. Place top on cookie.
Cut fondant leaves out and stick in frosting on top.
