Rinse the Dandelion Flowers thoroughly under cool water.

Combine the rinsed dandelion petals with boiling water and let steep in the refrigerator for at least 4 hours or overnight.

Strain the flower mixture through cheesecloth into a large bowl.

In a large pot, combine the strained dandelion liquid with lemon juice and pectin. Bring to a rolling boil for at least 2 minutes.

Gradually add sugar, continuing to boil for another 2 minutes until fully dissolved.

Ladle the hot jelly into sterilized jars, leaving about 1/4 inch of headspace.

Process the jars in a boiling water canner for 10 minutes.

Cool jars at room temperature overnight and check the seals after 12–24 hours.
