In a microwave-safe bowl, put 130 g raspberry (either fresh or frozen), 30g sugar and 2 tsp water and mix them well. Heat it in a microwave oven for 2 mins with 600w (or Medium power) without cover. Or you could cook it in a pan but using microwave is so easy and less washing up!

Take it out and stir well. Sieve it and the sauce is ready. If it isn’t thick enough, heat up another minute with 600 w.
