Follow these concise steps to create your very own hibiscus tea syrup:

1. Boil Water: In a medium saucepan, bring 2 cups of water to a boil.
2. Add Hibiscus: Once boiling, add the dried hibiscus flowers to the water.
3. Simmer: Reduce heat and let the mixture simmer for about 10 minutes until the color deepens, and the petals have steeped well.
4. Strain: Using a fine mesh strainer, strain the hibiscus tea into a separate bowl or jar, discarding the solid flowers.
5. Sweeten: While the tea is still warm, stir in sugar (1 to 1.5 cups based on your preference). Add vanilla extract and lemon juice, if using, and mix until dissolved.

Your syrup is now ready to cool and be bottled!
