Separate the petals from the green parts of the flowers to avoid a bitter taste.

Boil the water and cover the petals with it to rest overnight (24 hours).

Prepare clean glass jars.

Strain the liquid through a fine mash sieve into a measuring jar.

Add water to have 3 cups of liquid.

In a pot, bring the liquid to boil, add the citric acid, sugar and pectin and leave to boil for 5 minutes.

Skim off the foam, if any.

If your jelly color is not satisfactory, my solution is to add 2 drops of food color.

Pour the jelly into the clean glass jars and let them cool.
