Notes
The sauce: Of course you may change the ingredients like going for black currants, blackberries etc. It’s also possible to use only jams (especially if in winter) or use only fresh berries (e. g. in summer). If using only fresh berries think of adding some tbsp of icing sugar for the sweetness. Adjust to your taste.Lemon zest & limoncello: If you prefer an orange flavour just add grated orange zest and orange liquor instead of... You may also go for a pure vanilla flavour.Don’t freeze the cake.
