Spiced Greek Yogurt And Buttermilk Cornbread

"Cornbread heaven: creamy and luscious interior made so with buttermilk and Greek yogurt. Crackly exterior made so with brown butter. And a spicy surprise of fennel seed, cumin seed, and Aleppo baked right into the crust. A complex flour mixture of @bobsredmill cornmeal, dark rye flour, and wheat germ. Perfect as a complement to that big brown bird."
