Finally, after what felt like an eternity of sleep later, I drained the sugar/water from the ginger into a saucepan and brought it to a boil. Reduced the heat to medium to simmer, uncovered, for 10 minutes. then I poured the syrup (it’s almost syrup now) back on top of the ginger in the heat-proof bowl. The plate went back on top, and the bowl is sitting again at room temperature for 2 days. I can’t sleep that long.
…but I wait.
