In a shallow bowl, mix the milk, eggs, vanilla and sugar until combined. Put the matzah in the liquid, add the raspberries and mix well.
Allow the mixture to rest for 5 minutes
Warm a frying pan on a medium heat, and add a knob of butter. Once melted, place heaped tablespoons of the mixture in the pan, and cook for about 2 minutes from each side, until nice and golden.
