For a smoother butter, use an electric mixer on low speed to combine the ingredients. Adjust the amount of gochujang to suit your spice preference. Start with 1 1/2 tablespoons and add more for a bolder flavor. For a vegan option, substitute the butter with a plant-based alternative and the honey with maple syrup or agave nectar. Gochujang butter can be stored in the refrigerator for up to 2 weeks or frozen for up to 2 months. Thaw in the refrigerator before using.
