First, the Gardiner Museum has a special exhibit: "From the Melting Pot into the Fire: Contemporary Ceramics in Israel." This sculpture by Mirvat Issa is titled "Our Daily Bread." Obviously, it consists of ceramic pita breads freshly puffed in the oven. The exhibit is very tuned to life in Israel in a very positive way; depictions of buildings, dancers making ceramics while dancing, and reflections on ancient and Biblical history.
Of course most of the ceramic works on display were intended as vessels for serving, cooking, or dining -- intensely food related. But some of the works also made direct reference to food.
From the Chinese collection: a plate from the era 1625-1645 depicting the manufacture of salt. In my experience, this is a very special piece because it represents essentially a peasant activity.
