Step 1

Preheat the oven to 180C/160C Fan/Gas Mix the biscuits with the melted butter until thoroughly combined. Press into a 23cm/9in round flan tin, pushing the crumb mix up the sides of the tin. Bake for 10–12 minutes, then remove from the oven and leave to cool completely.

Step 2

To make the filling, put the egg yolks and lime zest in a bowl. Beat until the yolks are foamy and greatly increased in volume, then whisk in the lime juice and gin, followed by the condensed milk. When everything is completely combined you should have a thick, pourable batter. Pour this into the crust, then chill in the fridge for several hours or preferably overnight.

Step 3

To make the glaze, soak the gelatine leaves in cold water for about 10 minutes, or until soft, then squeeze out the water. Meanwhile, gently heat the lime cordial in a small saucepan. Stir the gelatine into the warm cordial until completely dissolved. Stir in the gin. Strain into a jug and leave to cool completely.

Step 4

Pour the cold but still liquid glaze over the filling and return to the fridge to set.

Step 5

To make the chocolate drizzle, melt the chocolate with the butter and golden syrup until very smooth. Allow to cool until just warm but still liquid. Drizzle in lines over the set glaze (make sure the glaze is well chilled, otherwise it may melt).
