Flamiche

Flamiche is a French savoury pastry, originating in the north-west France. It dates to medieval times and originally was a kind of galette, but in its modern version is a tart made with leeks and cream. Two possible derivations have been advanced for the word flamiche: either that it comes from flamme, 'flame', as the dish was traditionally cooked in a wood-burning oven, or that it is a corruption of vlamiche – Flemish (the dish being native to north-west France, close to the border with Flanders).
