Take vermicelli in a bowl & crush it using your hands.
Take a small bowl & mix soft butter & red food colour.
Mix well.
Add this butter to the vermicelli.
Mix all preferably with hands so that the entire batch of vermicelli is coated thoroughly and become little moist. But don't over do.
Grease the baking pan (ours is 6 inches round) with butter.
Put some vermicelli & firmly press it on the sides of the greased pan. Make a kind of wall with the vermicelli around the sides of the pan so that the cream will remain confined to the vermicelli & will not flow out during the baking process.
Put some vermicelli at the base of the baking tin as well and pack the vermicelli as tightly as possible with the help of potato masher. You can also use the bottom of a cup/katori to pack it tightly.
Pour in the cream filling and spread with a spatula into an even layer.
Take the rest of the vermicelli & spread it over the cream filling & lightly press it.
Transfer the pan to the oven and bake for 20 to 25 minutes.
Remove the kunafa from the oven and immediately pour on the sugar syrup, starting from the edge and moving towards the center, in a circular motion, making sure to cover the entire surface. You can also reserve some syrup for drizzling over individual servings if desired.
Let the kunafa rest until warm or completely cool.
Invert on to a serving plate.
Garnish with thinly chopped pistachios and dry rose petals.
Cut and serve by drizzling more sugar syrup.
