Add the honey and crushed red pepper flakes (or jalapeño slices) to a medium sauté pan or saucepan. Heat over medium heat until the honey very lightly begins to simmer. Give the mixture a quick stir to combine, then remove pan from the heat.
Let the mixture rest for 10 to 15 minutes so that the flavors can infuse.
Give the honey a quick taste to test the heat level. If you would like a spicier honey, you’re welcome to add more red pepper flakes (or jalapeño slices) and/or let the mixture continue to infuse for longer.
Once the honey has reached your desired heat level, strain the honey through a fine mesh strainer into a clean storage jar. Stir in the apple cider vinegar until evenly combined.
Use the honey immediately or see instructions below for storage instructions.
