1. Adjust the oven rack to the middle position and heat the oven to 350°.
2. In a small saucepan over medium heat, or in the microwave, melt the butter and honey together.
3. In a large bowl, combine the graham cracker crumbs, butter-honey mixture, lemon zest, and salt. Spread mixture into the bottom of a 9-inch pie pan. Use the bottom of a glass or a dry measuring cup to press the crumbs evenly and firmly over the bottom and up the sides of the pan.
4. Bake for 10 to 12 minutes, or until the crust begins to set and has browned slightly. Let cool.
