This is my familys favourite cheesescake and one I make for most gatherings of the clan!! It freezes well if you want to prepare ahead. Just line the pan with tinfoil and when set lift out or leave in tin and place in plastic bag and freeze. Remove from freezer a few hours ahead of needing and decorate with rosettes of whipped cream around edge and sprinlke with chocolate curls or place thin slices of lemon cut in half and twisted onto each rosette of cream. NOTE: biscuits = cookies * Cook time does not include setting time.
