Hi H - cheesecake:- make a biscuit base (usual biscuit crumb / butter mix); make a coulis of stewed damson and sugar, boil & then simmer for 30 mins, pass through a seive and set aside. Make the topping - ricotta, cream cheese, vanilla, sugar & egg whisked together. Top the biscuit base and bake in med oven 50 - 60 mins. Top with the reserved coulis and extra stewed damson - stone out.
Finish with swirls of mascarpone whipped with a little ginger and mint and more coulis round the edge making it look all cheffy.
If you can't be bothered to bake the cheesecake - make the biscuit base, top with sliced damsons, mascarpone & ricotta whipped with a little damson gin for flavour, and serve with the sauce over the top.
Savoury sauce: Slice onions and gently fry over low heat. Add pitted damsons and simmer for 10 mins. Stir in chopped fresh basil, currants (or apple pieces), a little all-spice and some ginger, red wine vinegar and brown sugar. Simmer for 10 mins. Remove from heat and pass through fine seive. Serve with lamb, goose, fish etc.
Stewed damsons will go mushy if left for too long. If combining with apple its best to have them with some texture. The skins are part of the character, so I would just half and stone them, add the apple, a dash of good brandy and top with crumble mix - add some crushed walnuts for a nice nutty extra.
