French Macaron Baking Adventures, Part 12: Blueberry Macarons

Blueberry macaron with homemade blueberry preserves

I baked two batches of blueberry macarons last month and achieved different results. This was the first time I used a natural powdered colorant. With this type of color, you’ll need to use a bit more of it if you want a vibrant color.


The powdered colorant can be added during the meringue process or can be blended in advance with the almond flour/powdered sugar mixture.

Recipe #1 contained blueberry ganache filling. Even adding more cooked blueberries didn’t help as it still tasted like white chocolate. The color was a medium shade of blue.

Another change was the oven. I baked the macarons in a smaller counter top model. The oven reached the temperature in a short time, and it was properly calibrated. The problem was there were only 2 racks and 2 levels. That meant the tray levels were either too close to the top or lower heating elements. I put my first tray on the bottom level and shielded it with an empty cookie sheet to prevent further browning. Also, all shells were baked on parchment paper covered trays.

The results of blueberry batch #1 featured browner than blue shells. The color of the blueberry ganache was lovely but only adding a fresh blueberry in the center gave the macaron any real blueberry flavor.

For batch #2, I used the quick ‘n’ easy method for making preserves. I pulverized 8 ounces of fresh blueberries with a potato masher as I didn’t want to get the food processer dirty and have to wash it. Then I added more than a cup of granulated sugar, stirred at a rolling boil and preserved it with liquid pectin. I followed a recipe in a book for baking cupcakes and the amount of pectin was far too much. I’ll be making this batch again with less pectin and see how it works. Too much pectin makes it more difficult to pipe.

More of the powdered blue colorant was used and I mixed it into the almond flour/powdered sugar mixture. The standard oven was used so the results were slightly better because I used the middle rack. However, I shielded each batch by putting an empty a cookie sheet in the rack above it. That meant the temperature never reached 350—instead it averaged 335. So, while the macarons have feet and aren’t burned, they are as hollow as most of my other batches.

I also used only silicone mats to see if there was any difference. I prefer them because it’s usually easier to remove the macaron shells.

The second batch tasted better, more like a true blueberry macaron.
