50ml strong coffee with 1 tbsp Kalhua {or just strong coffee}
Cream topping
300gmascarpone
25gicing sugar
Cocoa powder to dust over
Instructions
Tart base -8”
Place digestive biscuits in a processor and blend to a fine meal. Stir in melted clarified butter/ghee.
Work up the sides of a tart tin, then press firmly to make the base.
Place in the freezer for an hour while you make the chocolate and cream filling. Once chilled and firm, gently loosen the edges of the chilled tart shell and return to the tin in the freezer.
Chocolate filling
Heat the cream to almost boiling. Add the chocolate and coffee and leave covered for 15-20 minutes until the chocolate softens. Whisk until smooth.
Coffee cream filling
Whisk together all the ingredients in a glass bowl.
Microwave for 30 seconds, whisk again. Repeat until the cream begins to thicken at the edges, 4-5 times. Cool, whisking now and then to keep the cream uniform and to prevent a film from forming on top.
Note: You can also make this on the stove top. Stir constantly.
Cream topping
Gently mix the mascarpone and icing sugar until smooth. Don't overmix.
Assembly
Gently pour the chocolate filling over the base of the chilled tart base and spread to cover base. Top with a circle of whole digestive biscuits. Moisten the biscuits with the coffee-Kahlua mix, then pour over the cool coffee cream.
Leave to set in the fridge overnight.
Pipe over with the mascarpone and dust with cocoa powder
