No relation to the pungent paste — at least, not directly. This sandwich board was stationed on the sidewalk outside a casual eatery whose patrons are chiefly Brazilians, not Brits, and "marmitex," I later discovered, is Portuguese for "box lunch." Likely it shares an etymology with "marmite," the steep-sided, covered French cookpot. As it happens, the British sandwich spread was originally sold in an earthenware container that resembles a marmite — which nowadays is still depicted on the label.
