This is one of my favourite desserts, it is not too sweet and the luscious custard is a perfect finish to any meal.
The crispy/crunchy topping is a fantastic contrast to the custard.
You do need to plan a little with this dessert, but only from the point of ensuring that you leave enough time to allow it to cool and set in the fridge. It takes about 15 minutes to mix all the ingredients together then in the oven for 30 minutes and the rest of the time is leaving it to set. So make it earlier in the day and then just before serving you top with the sugar and melt the sugar so you get the crispy topping.
