Israeli cuisine includes local dishes as well as dishes brought to the country by Jewish immigrants from the diaspora. Since the establishment of the State in 1948, and particularly since the late 1970s, an Israeli fusion cuisine has developed. Roughly half of the Israeli-Jewish population attests to keeping kosher at home. Kosher restaurants, though rare in the 1960s, make up around 25% of the total as of 2015[update], perhaps reflecting the largely secular values of those who dine out. Hotel restaurants are much more likely to serve kosher food. The non-kosher retail market was traditionally sparse, but grew rapidly and considerably following the influx of immigrants from Eastern Europe and Russia during the 1990s. Together with non-kosher fish, rabbits and ostriches, porkoften called "white meat" in Israelis produced and consumed, though it is forbidden by both Judaism and Islam.
