In a small saucepan over low heat, stir together the honey, crushed red pepper flakes, and garlic powder. Keep stirring and simmering on low for about 3 minutes. Watch the mixture carefully to ensure it doesn't reach the boiling point, and to make sure it doesn't burn.
Remove the saucepan from the heat and pour in the apple cider vinegar, then stir. Allow the mixture to sit undisturbed for about 10 minutes.
If leaving the red pepper flakes in to increase the heat/spiciness of the sauce over time, go ahead and pour the slightly cooled mixture into a mason jar or other airtight container with a lid.
If you prefer the hot honey to be milder, strain out the red pepper flakes while pouring the hot honey mixture over a fine mesh sieve placed over a large bowl. Pour the hot honey sauce into a mason jar or other airtight container with a lid.
Ensure the lid is on tight, then store hot honey sauce in a pantry or other cool, dark place for up to 6 months.
Notes
Makes approximately 6-8 ounces. Spice level: you can adjust the heat of this homemade hot honey sauce by using more or less pepper flakes. Also, the heat intensifies the longer the red pepper flakes sit with the other ingredients in the jar. If you want less spice/heat, strain out the pepper flakes before pouring into a jar.Storage: Store in an airtight container like a mason jar with tight-fitting lid in a cool, dark place, like a pantry or spice drawer, for up to 6 months.
