Blueberry Lemon Macarons

“In everyone’s life, a little rain must fall.”

The words my boyfriend told me after making this version of macarons. The last time I made macs, I used the recipe from Bravetart. It cut baking time significantly, however, my taste testers said they preferred the Pierre Herme recipe because they were “gooeier.”

I decided I was going to conduct some experiments this time around. Instead of 115 grams of Almond flour from the BraveTart recipe, I would use 200g. Pierre’s recipe has 300 grams Almond flour to 300 grams confectionary sugar so I thought 200 grams to 230 g was a good idea. Well, the shells were definitely softer, but almost all them cracked. I could blame this on a few things. Instead, I am just going to chalk it up as a failed attempt.

macs3Obviously, I haven’t found the right ratio. I want to incorporate what I learned from both recipes. I may try next the 1:1 ratio for flour and sugar, but keep the egg white process from Bravetart and see how I fare… To be continued.

My second experiment was using natural food coloring. Since these were going to be a blueberry lemon, I pureed some blueberries in a blender. I started off with a small amount because I didn’t want to overdo it. The puree turned the dough into a soft blue. A complete surprise since it was a dark purple? But hey, good to know for the future.


  • 200 g Almond flour
  • 230 g Confectionary sugar
  • 144 g egg whites
  • 72 g sugar
  • 1/2 tsp kosher salt
  • 1/4 cup blueberry puree

Preheat oven to 300F. Sift the almond flour and powdered sugar into a large bowl. Set aside. In a standard mixer with the whisk attachment, add the egg whites, sugar, and salt. Beat on medium (level 4) for three minutes. Increase speed to a level 6 for another three minutes. Then increase the speed to a level 8 for another 3 minutes. Add the puree and mix at level 8 for another minute.

macs1Fold in the egg whites to the flour mixture to break down the egg whites. Put the batter in a pipping bag and pipe on a prepared baking sheet. Bake for 14-18 minutes. Since my oven gets super hot, I put a wooden spatula between the door of the oven to let moisture escape. It is supposed to prevent the shells from cracking which they still continued to do. Whomp.


  • 1/2 -1 squeezed lemon
  • 1/2 cup blueberries
  • 1 stick butter
  • 3 cups confectionary sugar

In a standard mixer using the paddle attachment beat the butter on high until it becomes light and fluffy. Scrape down the sides using a spatula and add the blueberry puree and 1 cup of confectionary sugar. Mix until well incorporated. Add confectionary sugar cup one at a time until the buttercream starts to take shape. Pipe frosting into cooled shells and store in freezer in an air-tight container. Allow macarons to sit in the fridge for at least a half hour before serving.
