When I lived in the States, I had a friend named Lori who made the best Blueberry Buckle you've ever tasted. Recently, I picked up a big bag of frozen organic blueberries at Costco (NT$399), and I have finally found a great recipe that (almost) rival's Lori's. Thank you, Martha Stewart. Blueberry Buckle is easy to make if you have the frozen blueberries. And you can actually buy "Crumble topping" at Jason's if you're too lazy to make your own topping. I added pecans to mine and drizzled honey over the top.
