Freeze The Main Ingredient For Perfect Blueberry Cookies

Standing in your cozy kitchen, you're excited to embark on your next home-baking adventure. Today, your heart is set on creating a batch of delectable blueberry cookies. But a pressing question arises as you're creaming the butter and sugar: Should you use fresh, freeze-dried, or pre-frozen blueberries to bake the best blueberry cookies?

You've heard various opinions, read countless recipes, and saved trick after trick found on social media, each advocating for a different approach. Fresh blueberries promise vibrant flavor and make sense, while freeze-dried blueberries boast concentrated intensity. You also won't have to worry about overly wet cookie dough. And then there are pre-frozen blueberries, which seem to straddle the fine line between convenience and taste. The uncertainty weighs on your mind.

But wait, there's a game-changing twist you've yet to explore — freezing the main ingredient, the fresh blueberries first, then thawing them. The idea might sound counterintuitive, but a magical transformation occurs when blueberries are frozen, then thawed. The blueberries will release their natural juices as they thaw, turning irresistibly soft, juicy, syrupy, and jammy, making them easy to mix into your wet ingredients and seamlessly integrate into the cookie dough. This phenomenon intensifies their flavor, elevating the taste profile of your fresh blueberry cookies to new heights. 

Not only that, your blueberry cookies will have a beautiful blue-purple (or periwinkle) hue that's derived naturally. The thawed blueberries are the magical ingredient that will give cookies structure and create a blueberry-muffin-like taste, as Justine Doiron shared on TikTok. We're sold! To get started, freeze your fresh blueberries. One of the best ways to do this is to wash and dry fresh, plump blueberries. Next, lay your blueberries in a single layer over a sheet or baking pan. Place the pan into the freezer and freeze the blueberries for at least 12 hours or overnight. Then, thaw the blueberries. This can be achieved over the stovetop or microwave for the impatient. The thawed blueberries will be soft, syrupy, and perfect for mashing into the cookie dough like a puree. 

As the cookies bake in the oven, the science behind the frozen-then-thawed blueberries takes center stage. The thawed blueberries release their juices into the dough, creating pockets of jammy goodness and adding structure and a delightful moistness to the cookies. They also lend a natural sweetness that balances the cookie's rich buttery crumb, making them an ideal and beautiful periwinkle treat for any occasion. Thus the extra steps of freezing and thawing the blueberries will be worth it.
