With dandelions harvested/weeded at Bon Secours today, I made dandelion root tea. To make it you need to wash the roots of dandelions from soil without lead or chemicals. Chop the roots into extremely fine pieces* and roast them in an oven or toaster oven until they're dry (like tea) then cook with water over the stove. I used a normal water to tea ratio amount.
Aside from knowing I could identify dandelion and knowing where not to get dandelion roots from, I didn't really know what I was doing. It tasted a little nutty and also was delicious.
I've heard dandelion tea (which is also called dandelion root coffee) is medicinally used as a diuretic.
