Collect 4 cups ( or more) of the violet blossoms. Try to pinch off the stems. Boil 4 cups of water and pour that over the blossoms. The water will turn anywhere from a vivid blue to almost black. Let it steep for 24 hours. (Can do less time if you want). I covered mine and put it in the refrigerator overnight. Strain the liquid. I also squeeze all the water I can out of the petals. Throw the spent blossoms out. ( I toss mine into the chicken yard). Take 4 cups of the "violet tea" and add 2 or 3 Tablespoons of lime juice ( or you can use lemon juice). The color will change to purple!!Do tell? How do I make violet jelly?
Pour this into a deep pot. Bring to a roiling boil. Add 1 package pectin ( I use the low sugar/no sugar type). Bring back to a boil, stirring constantly. Boil 1 minute. Add 3 cups sugar (all at once). Stir to dissolve and then bring back to a roiling boil. Boil 1 to 2 minutes. Remove from heat. Skim off foam. Fill prepared jars, wipe rims, place on lids and rings and place into a water bath. Bring to a boil ( slow boil). Process 10 minutes. Remove from heat and take out of the water bath ( I place mine on a towel) left set 24 hours. Check lids to see if they sealed. Any that didn't seal need to go into the refrigerator. The rest are good on the shelf until opened, then they go in the refrigerator. Good on shelf for 18 months.
