Ingredients:
- 4 cups fresh lilac blossoms (Lilac vulgaris, pesticide-free; stems removed)
- 4 cups boiling water
- 2 tablespoons lemon juice
- 4 cups infused lilac tea
- 4 cups granulated sugar
- 1 packet powdered pectin (1.75 oz / 49g)
Instructions:
- Carefully inspect lilac blossoms, removing any stems and green leaves. Gently rinse and pat dry.
- Place prepared lilac blossoms in a large heatproof bowl or pot. Pour boiling water over the blossoms. Add lemon juice.
- Cover and let steep at room temperature for at least 2 hours, or up to overnight for a stronger flavour.
- Strain the lilac infusion through a fine-mesh sieve or cheesecloth-lined colander into a clean saucepan, pressing gently to extract all the liquid. Discard the spent blossoms.
- Add sugar and powdered pectin to the strained lilac infusion. Stir well to combine.
- Bring the mixture to a rolling boil over high heat, stirring constantly. Cook until the mixture reaches the jellying point (220°F / 104°C on a candy thermometer, or until it sheets off a spoon). This will take approximately 5-10 minutes.
- If necessary, skim off any foam that forms on the surface.
- Carefully pour the hot jelly into sterilized canning jars, leaving ¼ inch headspace. Wipe the rims of the jars clean. Place lids and rings on the jars, tightening to fingertip tightness.
- Process in a boiling water bath canner for 10 minutes (adjust for altitude). Alternatively, let the jelly cool to room temperature and store in the fridge for several weeks.
- Let the jars cool completely, undisturbed, on a wire rack. You should hear a 'pop' as the jars seal. If a jar doesn't seal, refrigerate it.
