This is an unusual tart which can be baked all year round using elderflower cordial, but it is best to use fresh elderflowers when available (in June and July). It is a variation of a cheese tart using only fresh or stale breadcrumbs. Elderflowers have strong medicinal credentials and were used by witches in Medieval England. Traditionally, the flowers were infused into wine, cordials and vinegars and were also used in elderflower fritters, now reappearing on modern restaurant menus. As well as being an interesting pudding tart, this tart can be eaten outside set meal times with a glass of elderflower wine or champagne.
