I remember posting this question a while back, but a search didn't turn anything up. So here I am once again, about to make a recipe that calls for lemongrass but I have none. I have the dried stuff in a jar, but was advised by wise hounds that it is a poor substitute, and I found that to be the case. I even soaked it in boiling water but found it lacking. Will anything else do? Would grated citrus zest (lime and/or lemon) come close? I'm tried a few local markets (including Fairway) and found none, and am not in a position to run down to Chinatown or even another neighborhood, thanks to torrential rains and a sick baby. Thanks for any suggestions.
