Rekha's Notes
Slice the ginger thinly rather than in large chunks for faster, stronger flavor.
Start with a milder batch since it is easier to steep a second, stronger batch than to fix an overly sharp one.
Leave the ginger skin on, it is edible and adds flavor, and it gets strained out before drinking.
Storage: keeps in a sealed jar in the refrigerator for up to 4 days. Freeze extra in ice cube trays for up to 3 months.
