Dandelions? Don't they turn your teeth yellow? Seriously tho...dandelions? Never woulda thought...
Dandelion Leaves are harvested in very early spring, before the buds appear at the center of the plant at ground level. After the buds appear the plant gets a little too bitter, as the plants juices move up from the root. Tastes a little like Endive and makes a good salad with hot bacon dressing. Since you live in Pa, alot of Gun Clubs, Churches and Fire Company's will be having Ham and Dandelion Dinners as Spring and Easter approach. Keep your eyes open for such weekend dinners. You may like the taste.
To my knowledge, the flowers are used in wine making, not cuisine. Dandelion Wine has a pretty potent kick to it, and can make standing up, after a glass full, an experience.
