This is so basic it’s hardly worth writing, but for my own records, it was great.
500 g rhubarb stems (weighed after trimming)
2/3 cup sugar
juice of 1 decent-sized lime
a good glug of Cointreau
Cut the rhubarb into 3 cm lengths. Put in a baking dish, and toss together with the sugar, lime and Cointreau. Roast, uncovered, at 180 C for about 20 minutes, until the rhubarb is softened. The pieces will still be intact and beautiful red. Let it sit for a couple of minutes before eating, or eat cold later. Good with yoghurt for breakfast, or creme fraiche and crisp almond biscuits for dessert.
