For the honey, use the creamiest, thickest, and mildest honey you have. I've been using this honey lately. A day after posting, I corrected the amount of lemon juice from 1 teaspoon to 1/2 tablespoon.
Combine the honey, lemon juice, and coconut oil together in a small bowl and whisk to combine.
If your glaze has little white lumps, you can warm it for a moment and then strain the melted glaze to separate the white lumps. It's a bit easier to drip over the cake if the glaze is a bit fluid so you can warm it for a moment. To warm the glaze, place it in a warm oven for just a few minutes and then whisk to make it fluid and creamy.
