I put this ginger on top of most things - noodle dishes, soup, stir fries... I used to buy the bright pink ginger from the grocery store, but I like making it myself because I know exactly what's in it.
I pretty much followed these instructions, with some editing (and way less sugar)...
I did 100g of ginger, which is a nice amount. I also use a lot less sugar than most recipes state - I guess this means it won't keep for as long in the fridge, but should last at least 3 or so months.
1 tbspn sugar
1/2 cup rice vinegar
1/2 tspn salt
First comes the fun part - chopping the ginger! Okay, when I say fun I mean not-so-fun... Peel the ginger and break off the knobbly bits, so you have nice easy pieces to slice. For the small pieces just use a little knife and slice finely, for the bigger pieces try a grated or something like that.
Next, sprinkle the salt on and rub it through the ginger with your fingers. Sit for 1 hour.
After an hour, the ginger should be turning slightly pink and will be a lot more limp. Pick it up in your hands and squeeze so lots of the juice comes out. If you prefer you can pat dry with paper towel.
Finally, put the sugar and vinegar in a saucepan and heat on low until the sugar has melted. Pour over the ginger and push the ginger down - you may want to add a tiny bit more vinegar so that the ginger is covered.
That's it! Enjoy!
