Warm honey in a small saucepan over lowest heat until loose and pourable — do not boil.
Stir in red pepper flakes and steep for 5 minutes, stirring occasionally.
Remove from heat. Add apple cider vinegar, garlic powder, and salt. Stir to combine.
Taste and adjust heat or tang. Strain for smooth sauce or leave chunky.
Cool completely before storing. Sauce thickens as it cools.
Notes
Store at room temperature in a sealed jar for up to 2 weeks — do not refrigerate. Improves over 24 hours as the heat continues to infuse. Scale up easily — ratio stays the same for larger batches.
