How to Make It
Preheat the oven to 400° and line two 12-cup muffin tins with paper or foil liners. In a medium bowl, whisk the all-purpose flour with the cornmeal, rye flour, baking powder and baking soda. In another medium bowl, whisk the buttermilk with the oil and honey.
In a stand mixer fitted with the paddle or using a handheld electric mixer, beat the butter, sugar and salt at medium-high speed until light and fluffy, 1 to 2 minutes. Beat in the eggs 1 at a time, scraping down the side of the bowl as needed. Add the dry ingredients and beat at medium speed until evenly combined. At low speed, gradually beat in the buttermilk mixture until just incorporated, then fold in the corn.
Spoon the batter into the prepared muffin cups. Bake for about 15 minutes, until a toothpick inserted in the center of the muffins comes out clean. Let the muffins cool in the pans for 10 minutes before turning them out onto a rack to cool completely.
