The young ginger in the markets in late spring is very different from the old ginger that is available year-round. Yes, they are both a rhizome and come from the same plant but the former is harvested when the shoots are off-white with pink tips.
Young ginger is moist and tender with a very thin, edible skin and mild flavour. It is often eaten as a vegetable or made into a pickle.
Old ginger has been allowed to mature on the plant and the skin is thicker, the flesh fibrous and the flavour hot and strong, so it is usually used as a seasoning. Old ginger can be dried and then used to make ginger powder.
Young and old ginger should be chosen the same way: buy โhandsโ that have smooth skin and which feel heavy.
