Toast the festive season with our Christmas cocktail ideas, including sloe gin fizz and spiced negronis
Heat the oven to 200C/fan 180C/gas 6 and line a small roasting tin with baking paper. Arrange the rhubarb in one or two layers in the tin, then scatter over the orange zest and scrape in the seeds of the vanilla pod. Drop in the spent pod. Stir together the crushed cardamom and sugar, and sprinkle this over the top, then pour over the orange juice. Cover tightly and roast for 20-25 minutes or until the rhubarb is tender and the sugar has dissolved – the timing will depend on the thickness of the rhubarb. Cool.
Once cool, remove and discard the vanilla pod. Gently stir through the maple syrup to taste, mixing the roasting juices into the rhubarb as you go. Spoon into a jar and chill. Enjoy over porridge, stirred into yogurt or piled onto crumpets or meringues with whipped cream.
