Zest 1 of the oranges and the lemon over a bowl. Add the icing sugar, mascarpone and 2 tbsp of the lemon curd and swirl together.
Cut the peel and pith from both oranges, then slice or segment. Heat the remaining 2 tbsp lemon curd in a pan, tip in the orange slices and warm through for 30 secs.
Top four warm pancakes (see our easy pancakes recipe) with the citrus mascarpone, then fold over and top with the warm orange slices. Drizzle over any juices from the pan.
