When annually attending the ITB tourism show in Berlin I'd go to the Judische Gemeinschaft in Berlin with a Yiddish-speaking orthodox friend to have dinner and sometimes met elderly survivors. He'd speak Yiddish to them and I'd speak my klein schlechtes Gymnasium Deutsch, augmented by hitchhiking through Germany in 1973 and many business and Erasmus exchange teaching trips to Germany since.
Most mornings my Russian-Latvian wife makes kashu. I also married into excellent borscht, chicken bullion-chik, vorschmach and carp baked in tinfoil for New Years. It's like I married my grandmother.
