Buyers seem as interested in the trinkets as in the tart.
As a final touch to the scenario, there's a cardboard crown. Raymond Ost, co-owner and chef of Sandrine's on Holyoke Street in Cambridge, explains this longtime tradition. The tart has an almond filling and tastes delicious, but most important is the serving ritual. Ost says, displaying a handful of tiny Victorian ladies and gentlemen that will go inside his galettes. To find that person, a kid, usually the youngest, hides under the table.
