This is yummy and easy to prepare as well.
Do this rich rose mousse for your dad.
He loves it for sure.
It can be taken either as a dish itself.
Or, can be taken as a dessert after a full course dinner.

All you need:

Place the rose water in a small heatproof bowl.
Sprinkle the gelatin over and set aside for 15 minutes,
until the gelatin is spongy. Stand the bowl in hot water
and stir until the gelatin has completely dissolved.

Place the egg yolk, superfine sugar and vanilla extract
in a bowl over a saucepan of hot water and
beat until thick and very pale.

Remove the bowl from the pan, beat until cooled slightly,
then stir in the gelatin. Stir in coloring, if liked.

Whip the cream until it stands in soft peaks,
then fold it into the mousse mixture.

Whisk the egg whites until they stand in stiff peaks,
and fold into the mousse.

Pour the mixture into 6 glasses or glass dishes
and chill for several hours.

Serve the mousse with frosted roses
or rose petals in a stemmed glass.

Once done it will be a great treat for your dad.
