I started with just buying ginger from the grocery store and cutting it like you would when planting potatoes. You will see little "nodules" on the ginger. That is where the tops grow from. Make sure each peace has one or two of those when you plant them. Each piece I plant usually gives me about 1/2 lb of ginger or better.

I get these Ginger Honey Crystals from "Prince of Peace" (Prince of Peace..... Made in China..... Has a Proverb on the packaging. Hmm.)
I'm thinking I could make some strong ginger tea with these crystals (real ginger+honey+sugar) and then mix it half and half with seltzer water.
This has turned into an auspicious Sunday morning. I thank you, CB. And my arthritic left knee thanks you.
