Crush the digestives in a bag with a rolling pin, and then pour in the melted butter and mix thoroughly. Tip this into an 8-inch springform cake tin and push down with a straight-edged glass until one solid mass.

Cut roughly half of your strawberries on top and vertically, and line the outside of the tin, placing the flat side on the biscuit base. Put blueberries on the bottom, just to cover the biscuit base and refrigerate for 15 minutes.

Whisk the cream cheese, vanilla essence and icing sugar until fully combined. Whilst mixing, pour in the pot of cream and mix until one thick, smooth consistency.

Tip roughly half of the mixture into a bowl and add a tiny bit of red food dye, just to turn it pink (optional)

Take the base out and then tip onto it a 3rd of the white batter. Then half of the pink. Then another third of the white. Then the pink. Then add dollops of white batter around and swirl with a skewer. Refrigerate for 5 hours or overnight.

Whip the cream and lemon zest to stiff peaks. To remove the Cheescake, place the cake tin onto a can and gently run a knife around the edges. Then remove the outside and transfer the cake to a stand with a spatula very carefully, being sure to have removed the metal base in the process.
