Now that you have your petals collected dump them in a pot with your 5 cups of water. The petals will float so push them into the water with a spoon continuously as you go. Bring the water to a boil and keep pushing the petals down into the boiling water. Once the petals become saturated turn down the heat a bit and let it simmer for about 5 minutes. The simmering petals will be very aromatic as they cook down. Remove it from the heat & strain out the petals with a fine wire mesh or cheesecloth. The water will have become a "broth" of sorts & will be a brownish golden color. Not to worry though, this is not the final color & it will lighten up once your sugar is added.
Set the stage for your jelly by setting out your sterile jars and lids.
In a large pot stir together 3 cups of the broth with 4 Tbs of lemon juice, and 6 cups of sugar. (you can add some yellow food coloring to brighten it a bit as well) Bring the mixture to a rapid boil until it can not be stirred down. Quickly stir in both packets of liquid pectin & return it to a boil. Boil it hard for 1 minute longer. Now you can fill your jars leaving 1/4 inch head space. Scoop the foam off of the top with a spoon & add the lids. Then process in a 10 minute water bath.
