Steep hibiscus in boiling water for about 30 minutes. The resulting liquid will be deep purple in color.
Add tomato paste, apple cider vinegar, honey, smoked paprika, garlic powder, onion powder, cayenne, ginger, and liquid smoke, to a small saucepan over medium heat. Stir until uniform.
Stir in hibiscus tea with petals. Bring mixture to a boil then reduce heat to low and simmer for about 15 minutes.
Remove hibiscus petals with a slotted spoon or strainer. Taste sauce and add sea salt and black pepper to your preference.
Use sauce to marinate, baste, or garnish grilled foods. See notes for storage information.
Notes
How long does homemade BBQ sauce last? Fresh barbecue sauce keeps for about two weeks. Store it in an airtight container in the fridge.Can I freeze it? Yes. Transfer the sauce into a freezer-safe, airtight container, leaving at least one inch of space at the top before sealing. Freeze for up to three months and thaw overnight before use.What if the sauce is too thin? Combine equal parts cornstarch and water in a separate container and mix vigorously to fully dissolve the cornstarch and create a slurry. Stir this slurry into the sauce until fully incorporated. Start with half a tablespoon of each ingredient and repeat the process if necessary, rather than adding too much at once.
