To make a batch of fireweed jelly you will first need to pick some fireweed flowers.You can find fireweed flowers growing in open fields and along road sides.
When picking fireweed, make sure that you choose a patch that is free of chemicals. Choose an area that is free of herbicides, pesticides, and chemicals from road runoff.
Harvest about four cups of fireweed flowers for the jelly recipe. Cut the flowers at the top of each stem, leaving behind the side shoots for later flowering.
Strain the flowers from the liquid using a fine sieve, and add to a pot with sugar, butter, and lemon juice. Bring to a rolling boil for one minute, and then remove from the heat.
