To make base blitz biscuits into a crumb. Melt the butter and add until it starts to bind. Place this mix into a baking tin pressing down firmly about a cm thick. Make sure tin has been greased. When base in tin put in fridge to harden

For filling put soft cheese and mascarpone cheese in a bowl. Add sugar and zest and juice of lemons. Whisk until smooth. Then add the egg yolks and eggs to mix and whisk again until smooth. Finally add flour. Taste to make sure you get the lemon flavour

Finally add the mix to the baking tin, poring on top of biscuit base. Place in oven 160 degrees for 40 minutes or until mix is set. Once cooked make sure it is placed in fridge to cool completely. Italian meringue for top is extra if you want to make it pretty:-) can explain how to do that if need. Hope this works for you
