[header] How to mince ginger [title] Trim the ginger. [step] Usually ginger comes in a big piece with branches attached at odd angles. Depending on the amount of ginger that you need, you may want to take a piece from the larger part of the root, or you may just want a couple of small branches. 
[substeps] If you are using all of the root, trim the branches, so that you can peel them separately. If a few bits of ginger skin don't bother you, don't trim the branches.
