It is also known as “crystallized stem ginger” or “candied ginger.”
Many people like to just gorge on this whole out of the package.
Buderim Ginger Limited in Australia is one of the largest companies in the world (as of 2004) for making crystallized ginger.
When chopping crystallized ginger, it may stick to your knife. If this happens, you can put the knife under running hot water, dip it in a bowl of hot water, oil it with a neutral oil, or, spray with a neutral-flavoured cooking spray.
1/4 cup finely chopped Crystallized Ginger = 1 tablespoon of freshly-grated ginger plus few pinches of sugar (or more, if you wish) = 1/2 teaspoon ground ginger
1/4 cup, coarsely chopped = 1.5 oz / 40g
Store indefinitely in sealed container. You can also freeze for up to 1 year (set out to thaw 3 hours before you need it.)
