“Bloom” the gelatin. Here is the process: Sprinkle the powdered gelatin evenly over 2 tbsps of warm water to keep lumps from forming. Set the gelatin aside for a few minutes until it swells or “blooms” as it absorbs the liquid. Melt the gelatin either in a hot water bath or in a microwave (for about 10 seconds on high) until it becomes translucent. Use your fingers to check that all the granules have totally dissolved.

Meanwhile, put the cream, sugar, milk and rum into a saucepan and slowly bring to a simmer. Heat gently for 30 seconds, then remove pan from heat. Taste it and add a little more rum if you wish.

Add the bloomed gelatin mix to the cream mixture and stir until fully dissolved.

Pour the mixture into four individual glasses or moulds. If you use glasses, leave enough room for the glaze. Leave to cool, then place the glasses/moulds in the fridge to set for at least two hours, or overnight if preparing ahead.

Purée raspberries with syrup, sugar, and lemon juice in a blender or food processor. Pour mixture through a fine sieve into a bowl, pressing on solids.

Once the pannacotta if set, top each pannacotta with a spoon of raspberry coulis to serve.
