In a bowl mix the gelatin powder and water. Leave it aside for the gelatin to bloom.

Simultaneously, pour the cream and the milk in a pot along with the sugar and warm it by stirring occasionally. No need to boil. Once the milk warms up, add the bloomed gelatin to the pot. And whisk for 5 minutes for the gelatin to dissolve completely.

Switch off the heat and pour the salted caramel. Give a whisk to dissolve it completely.

Pour it into individual jars and let it set in the refrigerator for 4 hrs.  

For the sesame brittle, before you start making the caramel, place a parchment paper in a plate or a tray. Next, in a heavy bottom pan add the sugar and the water. Once it caramelizes add the sesame seeds and give a quick mix. Pour it on the parchment paper and tilt the plate or the tray gently to spread it.

Leave it aside for 30 minutes to set. You could be able to remove it easily from the parchment paper. Snap it into bite size.

Garnish on the panna cotta with the sesame brittle before serving.
