Chef's notes
FROZEN BLUEBERRIES – Use 1 1/2 cups of frozen (not thawed) blueberries and toss with the zest and cornstarch. Do not mix the blueberries into the batter. Instead, spread the batter in the pan and top with an even layer of the blueberries followed by the crumble. If the frozen blueberries are mixed in to the batter, they can alter how the cake bakes and can also turn the batter blue.
