This one is too moist inside, baked in nonconvection.
These are perfect, baked in convection.
Same recipe, different results. All due to a button on my oven. I thought that having a convection oven meant pressing "bake" would automatically make it convection. Maybe it was due to the fact that I didn't exactly know what convection means. Basically, a convection oven has a fan in the back, and the heat is more evenly distributed than a gas oven. In a gas oven, the heat either comes from the bottom or top, making the heat uneven.
So if you have a convection oven, it would be easier to bake better macarons. :3 Good luck to you all~
