• Preheat oven to 400°. Generously grease the cups of a standard muffin pan, or a 12" skillet with butter or cooking spray.
• In a large mixing bowl, whisk the dry ingredients: flour, cornmeal, baking powder, baking soda, and salt. Grate the jalapeño into the flour mixture and whisk again. Set aside.
• In a medium mixing bowl whisk the Greek yogurt to loosen it. Whisk in the milk. When the milk is fully incorporated whisk in the eggs. When the eggs are incorporated whisk in the butter and maple syrup.
• Tip the wet ingredients into the large mixing bowl with the dry ingredients. Use a silicone spatula to combine them together, scraping down to the bottom of the bowl. Stir the ingredients together only until no flour remains.
• Use a 3-tablespoon scoop or a large spoon to fill the greased muffin cups about 3/4 full with batter, or scrape the batter into the greased skillet. Place into the hot oven and lower the temperature to 375°. For muffins, bake 12 - 15 minutes or until the tops are burnished golden brown. For skillet cornbread, bake for 18-22 minutes, until the top is burnished golden brown.
• If using a muffin pan, allow the muffins to cool in the pan for 5-7 minutes. Remove the muffins from the muffin pan and allow them to finish cooling on a cooling rack. If you are using a skillet, allow the skillet to cool on the cooling rack at least 20 minutes to allow them to set up before cutting and serving them.

Maple butter

• In a medium mixing bowl, whisk together the soft butter and maple syrup until light and fluffy. (This may take a few minutes to completely incorporate the two.) Spoon the maple butter into a small serving bowl and sprinkle with flaky salt and serve alongside the maple jalapeno cornbread.
