Budapest’s only kosher pastry shop is, you guessed it, inside the city's old Jewish Quarter. Frőhlich set up shop in 1953 when many more Jewish people lived in the neighborhood and long before it became Budapest's party center.
Instead of "Jewish cakes," Frőhlich actually makes traditional Hungarian tortes, pastries, and strudels including Esterházy, Dobos, and krémes. There're plenty of other pastry shops in Budapest that sell tastier goods than Frőhlich, but I enjoy coming here for the ambiance: Frőhlich is still a small, family-run business where little has changed since the opening over six decades ago. Although now mainly a tourist destination, a shrinking group of local regulars also appear from time to time. When in doubt, go for the krémes or the Gerbeaud layered cake.
The one cake that's disctinctly Hungarian-Jewish and available throughout the year at Frőhlich is flódni, a delicious layered cake packed with walnut and poppy seed spread, apple, and plum jam. The best time to visit Frőhlich is during the Jewish holidays, particularly Purim (usually in March), when a few seasonal filled pastries emerge behind the glass such as hamantash. During Hanukkah, as customary, they make sufganiyah, which are round, deep-fried jelly donuts.
