In a small saucepan, combine honey, hot sauce, red pepper flakes, and a pinch of salt.

Warm over low heat for 3–5 minutes, stirring occasionally. Do not boil, just gently heat until flavors combine.

Remove from heat and stir in apple cider vinegar, if using.

Let cool slightly, then pour into a glass jar or squeeze bottle.

Store at room temperature for up to 3 months.
