To make panna cotta, place milk, cream, sugar and orange zest into a medium saucepan. Using a teaspoon, scrape vanilla bean seeds into pan then add the pod

Stir until sugar dissolves and bring slowly to the boil over medium-low heat. Cook over low heat for 10 minutes, stirring occasionally. Remove from heat

Place boiling water in a small heatproof bowl. Sprinkle with gelatine and stir until dissolved. Set aside 3 minutes. Stir gelatine mixture into cream mixture

Strain cream mixture through a fine sieve into a heatproof jug

Evenly pour (using about 1/3 cup mixture per glass) into 10 x 1 cup capacity serving glasses. Cover each glass with plastic wrap and refrigerate for 5 hours or overnight until set

Before serving, defrost the frozen berries in a shallow bowl. To serve, spoon berries over the panna cotta

Sprinkle berries with icing sugar as the red currants in the mix are quite tart and require sweetening
