My sister, who lives in Basel, finally got a small Delonghi espresso maker. Visiting her, it struck me that the coffee she uses wasn't doing much in that machine. Initially, we attributed the problem to the local water, a solution rich in calcium. Despite my sister and her husband blaming the water for the less-than-stellar coffee, I was sure that the issue was the coffee they used. Every sip made me nostalgic for the brew I use back in Sunnyside, Queens, namely Harem. Then on a trip to Freiburg, across the border in Germany, we spotted a store selling my favorite beans. Just in the nick of time, as the store was about to close. But they sold us a bag and we brought it home and after reconfiguring her espresso machine, delivered terrific Harem coffee.
