Add honey and red pepper flakes to a medium-sized saucepan. Turn heat to medium and bring to a low simmer, stir and simmer for one more minute.
Remove the pan from heat and allow the honey mixture to rest for an additional 10 minutes.
Add apple cider vinegar and a pinch of sea salt to the pan and mix well.
Pour the hot honey mixture into a glass jar. Once cooled, place the lid on the jar and store it in a cool, dark place.
Optional: If you prefer, you can strain the red pepper flakes out. Let the mixture cool slightly, then strain it through a fine-mesh sieve into a clean jar to remove the pepper solids. Seal the jar.
Notes
Watch the honey closely as it heats to prevent boiling, which can cause it to thicken or develop a burnt taste.
Start mild, then steep longer or add more flakes if you prefer extra heat.
Use fresh peppers for more kick, but refrigerate afterward since they shorten shelf life.
Strain out the flakes for a smoother drizzle if desired.
Use a kitchen scale — one cup of honey weighs about 12 ounces because it’s denser than water.
Store properly: keep it in a cool, dark place for up to 3 months, or refrigerate if you’ve used fresh peppers.
For gifting: pour your homemade hot honey into small jars, tie with ribbon, and label it "Sweet Heat!" a favorite touch from my recent holiday cooking class, where it was the first thing to disappear.
