This colourful dessert is refreshing after a rich meal. Since citrus fruits are at their peak around holiday time, you can count on an intense and sweet fruit flavour.
Make ahead: You can bake the tart shell and mix the cream filling a full day ahead, but assemble the tart the day you wish to serve it, up to six hours ahead of serving. Store it in the fridge, uncovered, until serving time.
Note: If you don’t have a rectangular pan, use a 23 centimeter round tart pan with a removable bottom. And if blood oranges aren’t available, use a mix of tangerines or mandarins (two of each of these for each blood orange).
