Rock Cakes Episode 2 Ammonite Pavement video

The second in our #rockcakes series, baking parts of the Jurassic Coast, following the weeks of #GBBO. This week features the Ammonite Pavement, which is exposed at low tide on Monmouth Beach near Lyme Regis, in biscuit.

Recipe: 1)Pinwheel ammonites: 300g plain flour, 150g unsalted butter, 2 large eggs, 105g granulated sugar, 10g (or 1 tbsp + 2 tsp) cocoa powder, 2 tsp vanilla extract, black food gel and silver food shimmer spray. Beat together butter and sugar, add eggs, add vanilla extract, mix in flour until a doughy consistency forms. Add black food colouring. Divide the dough in half. Mix cocoa powder into the other half. Roll both halves separately into a square on clingfilm. Freeze for 45minutes. (Start making the biscuit pavement)*. Roll out doughs. Place one dough on top of the other. Trim the edge to make them the same size. Press them together slightly. With the short side in front of you (this will make ammonites with fewer swirls - younger ammonites, than if you roll with the long side in front of you), roll together to form a cylindrical log. Cover the log in parchment and chill in the freezer for 1 hour. Preheat the oven to 190 degrees centigrade (Gas 5). Line baking tray with baking parchment. Remove ammonite swirl mix from freezer and re-shape as required. Cut slices of the dough and add to the ammonite pavement*. Blend the doughs together slightly with a knife/fork to create chamber distinctions or use an ammonite-shaped cookie cutter. The ammonites will spread during baking so allow room for this. Add some extra ‘free ammonites’ on a separate baking tray. 2)Easy Bake Biscuit base*: Mix 2005 unsalted butter and 200g caster sugar, beat in 1 medium egg, add black food colouring, mix in 400g plain flour until a dough forms. Shape the dough into a ball and wrap in clingfilm. Now go back to roll together the ammonite swirls. Freeze for 1hour. Unwrap the dough and knead the dough briefly. Roll to roughly 3 mm thick. Place on baking tray and create areas for the ammonite swirls to sit in. Bake for 10 - 14 minutes until edges are turning golden.
