Making Magic At Home!

Blueberry Cupcakes

I was inspired to make Blueberry Cupcakes based on the Percy Jackson and the Olympians books for this month’s Fandom Foodies theme, Food of the Gods. Witchy Kitchen is hosting this month, follow the link to learn more about the #FoodOfTheGods challenge. The challenge is to:

Cook food inspired by classic myths – Artemis’s Ambrosia, Lakshmi’s Laddoos, Tlaloc’s Tamales – or modern interpretations inspired by the likes of Wonder Woman, Thor, Death Note, American Gods, or Percy Jackson. Whatever godly grub you can summon, the power is yours!

Blue food is a theme throughout the books. We learn why this is a thing in The Lightening Thief. Percy’s mother, Sally, is married to Gabe Ugliano. Gabe is an unpleasant guy and Percy doesn’t understand why she is with him. Early in the story Percy explains the blue food for us.

Gabe had once told my mom there was no such thing. They had this fight, which seemed like a really small thing at the time. But ever since, my mom went out of her way to eat blue. She baked blue birthday cakes. She mixed blueberry smoothies. She bought blue-corn tortilla chips and brought home blue candy from the shop.

I wanted to use blueberries to color my cake and frosting instead of blue food coloring. It turns out on the purple side of blue but I really like the flavor and the look. I used homemade blueberry jam for the filling and homemade blueberry buttercream frosting tinted with homemade blueberry syrup. I like to keep the fruit in my syrup, but one tip I learned is to strain the fruit out of the syrup before adding to the frosting if you intent to use a star tip to pipe the frosting. Some of the blueberries got stuck and it resulted in a different look, which I like as it reminds me of seaweed. So bonus this time!
