Gather about 4 cups of fresh dandelion petals and place them in a large bowl. Cover with 4 cups of boiling water and let steep overnight.

Strain the dandelion petals, gently squeezing them to extract all liquid, creating a rich dandelion tea.

In a medium saucepan, pour the strained dandelion tea (approximately 3 ½ cups). Add juice of one large lemon and sprinkle pectin over the liquid.

Place the saucepan over medium heat, bring to a rolling boil, and add in 4 cups of sugar all at once. Boil for an additional 2 minutes.

Ladle the hot dandelion jelly into sterilized jars, leaving ¼ inch headspace, run a knife around the edges, and wipe rims clean.

Process the jars in a hot water bath for 10 minutes, then allow to cool, ensuring lids seal properly.
