How do you color macarons? I’m not a big fan of food coloring, but you can achieve a dark color in a macaron by using food grade charcoal powder (available at Whole Foods). The dark colored macaron would be the backdrop blackberries and lime curd, which I thought would go well together. This was one of the most time-consuming treats to make. My sister wanted to take a special treat to her art class, but was worried about making these herself. She came over and we made the macarons together. They were super tasty. The macrons did spread, however, so they ended up being the size of a small burger or slider. The “macaronage” process is a tough one, and finding the right consistency is a huge challenge. We used this: https://www.thescranline.com/blackberry-macarons as the basic recipe (which we had to use a scale/metric system for measurements since it comes from a British website), and I made my own lime curd. My sister’s classmates were really impressed by these complicated cookies, and they liked the large size of the macarons.
