Hold the packaging under warm water for a few seconds (it will then be easier to pour out the contents).
Shake the bottle and squeeze the contents into a pan.
Melt the panna cotta, but don’t let it boil.
If desired, season to taste with fruit purée, for example (up to 20% of the whole mixture).
Divide among the verrines and leave to cool for a few minutes.
Cover well, place in the refrigerator and leave to set for 2-3 hours.
