Pour the cherries into a sieve and collect the juice. Drain the cherries, measure 700 ml of juice. Stir pudding powder, vanilla sugar and 5 tablespoons of juice until smooth. Bring the rest of the juice to the boil in a pot, stir in the custard powder, bring to the boil again. Simmer for 1 minute while stirring. Remove from heat, stir in cherries. Let cool down, stirring occasionally.
Dissolve the coffee powder in 200 ml of boiling water and let it cool down. Roast the almonds in a pan without fat until golden brown, take them out. Mix mascarpone, quark, sugar and lemon peel and juice. Whip cream until semi-stiff and fold in. Break 2 Viennese cakes into coarse pieces (use the rest for other purposes.) In a glass bowl, alternately layer the sponge cake, cream, stewed cherries and almonds, drizzle the sponge cake with coffee. Chill the trifle for at least 1 hour (can be prepared well and left overnight). Serve decorated with lemon balm
