Line two large baking sheets with baking parchment. In a small bowl, mix both sugars together. In another small bowl, mix the jam with enough food colouring to create a vibrant red colour.
In a clean, grease-free bowl, whisk the egg whites until they form stiff peaks, using electric beaters or a tabletop mixer. Add about a third of the sugar, whipping for 1 min or so, until stiff and glossy. Gradually add the remaining sugar until you have a glossy meringue that holds stiff peaks.
Heat oven to 120C/100C fan/ gas 1/2. Turn your pastry bag inside out and, using a spoon, paint three lines of coloured jam from the top to almost the end of the bag. Fill with the meringue mix and twist the end to close.
Holding the bag vertically over the tray, apply enough pressure to create a base, then quickly draw the bag upwards to create little points. The jam will give the meringues a stripy pattern as they pass through the bag.
Bake in the oven for 1 hr or until the meringues sound hollow when you lift one and tap the base - they should have a crunchy shell and not be too chewy. Leave to cool in the oven with the door closed, then store in a plastic food bag or airtight container until ready to use.
