Preheat oven to 350 degrees F.
In a large bowl, whisk together honey and eggs until thoroughly integrated. Stir in orange zest. Sift together flour, baking powder, and baking soda. Add slowly to egg mixture. Lightly grease a loaf pan with butter. Add the mixture to the pan and bake. After 30 minutes check for doneness with a wooden skewer. (If it comes out clean, you are done. If not, give it another 5 minutes and check it again).
