You'd need pectin, or else you'd have dandelion jello.
Vfem makes and sells it. I hear it tastes like honey. I need to give it a try too.
ETA: Yep, take off the green stuff, particularly the ones that turn down. They are bitter. I always remove them when I make dandelion fritters.
Sepals, I guess they are.
Journey, I cut about 1/4" above the base. How do you get those outside green ones off without losing quite a bit of the yellow?
Please explain the fritters. Recipe please.
