This ginger marmalade is great on top of peanut butter toast. It can also be used as a glaze for ham or chicken, substituted for any jam in baking or as a dip for lamb instead of mint jelly. I just used the ginger that was available in the grocery store. I picked the freshest ginger that I could and it was fine.
