This festive dessert is worlds away from traditional treacle tart, for which the canon dictates shortcrust pastry. Here, I’ve used ready-made puff for a light and flaky, custard tart-style case, which helpfully means that the whole thing can be thrown together in just 30 minutes. In the filling, date and golden syrups unite for a rich, deeply flavoured set, spiked with festive ginger, clementines and cloves. Minutes to make, moments to disappear.
