Mostra has come to be a word synonymous with rusk (paximadia) in the Mykonos dialect but it originally referred to a unit of measure for rusks, one mostra being one rusk. The word comes from the Italian mostrare, which means to show, and from the Latin monstrare, which means “to show, to indicate.” You can find delicous Greek rusks with barley and an old variety of wheat called dikoko or zea, low in gluten, as well as an array of other lovingly curated Greek ingredients on my online store here.
