NO-FUSS FRUIT TART... This is perhaps one of the most useful puddings you can have in your repertoire. Not that it is the job of a pudding to be useful: a pudding exists merely to delight. Still, dinner does need to be made, even when there’s precious little time for it and that should be a delight, too. So here’s the deal: there is pitifully little work to be done to make this berry-dazzler of a tart, and enormous pleasure to be derived from its consumption.
