- STEP 1
Blitz the biscuits in a food processor (or crush in a sealed bag) until you get fine crumbs. Gently melt the butter, then mix with the crumbs in a bowl. Press the mixture evenly into the base of a 20cm loose-bottomed round cake tin (no larger!). Chill in the fridge while making the filling.
- STEP 2
Put all remaining ingredients into a food processor and blend until smooth. Spread over the base, smoothing with a palette knife, but leave a shallow depression to contain the topping. Leave overnight in the fridge to set (or longer, which intensifies the ginger flavours).
- STEP 3
Remove from the tin and top with your chosen fruit, slice and serve with double cream.
