Met some friends for lunch at Katz's last Sunday. (We actually intended to eat at Clinton St. Baking Co., but battling the Sunday crowd at Katz's was much less painful than the 2-hour wait at Clinton St.) I ate half my pastrami sandwich and brought the second half home and stuck it in the refrigerator. I came home late Tuesday night and popped the meat from the sandwich into the microwave for 60 seconds while gently warming the bread in the toaster oven. Not surprisingly, nothing could salvage the lousy bread they use, but the meat was extraordinary. Due to the high fat content of the pastrami, it responded really, really well to being microwaved, and came out hot and juicy and delicious, perhaps even better than when served fresh at the restaurant. But whether or not it's better, it certainly was good enough to order extra meat when there to keep at home. Do they sell it by the pound in the deli (and is it a better value), or only by the sandwich?
