Wash the dandelion tops thoroughly. Cut the stems and roots and discard them, as they taste extremely bitter and should be used only if you are making Dandelion vinegar to use it as a herbal medicine.
Mince the dandelion leaves and flowers into fine small pieces. The vinegar's flavour will benefit with smaller pieces of dandelion.
Fill the glass jar with chopped dandelion leaves and flowers, leaving about 2 inches of space at the top.
Heat the white vinegar or cider vinegar until it is steaming hot.
Pour this hot vinegar into the jar to cover the plants.
Use a chopstick to remove all the air bubbles, running it around the edge between the jar and dandelion leaves and flowers.
Screw the lid tightly on the jar. You should also place a wax paper between the lid and the vinegar to prevent rust from forming on the lid.
Place the jar in a cool, dark place for six weeks to allow the vinegar to penetrate the dandelions.
After six weeks, strain the chopped dandelion leaves and flowers from the vinegar and discard.
Your homemade dandelion vinegar is ready. Store it in a cool, dry place and use as per your requirements.
