Heat milk and 50 g sugar in a pot. Add rice pudding and cook over low heat for about 25 minutes, stirring occasionally. Remove from the heat and let it cool down for about 15 minutes.
Pour the cherries into a sieve and collect the juice. Mix 4 tablespoons of juice with pudding powder. Boil up the rest of the juice and 25 g sugar in a small pot. Stir the pudding powder into the juice and let it simmer for about 1 minute.
Add the cherries and stir.
Caramelise 1 tablespoon of sugar in a small pot, add almonds and a little cinnamon and mix. Put almonds on a baking paper, spread them out and let them cool down.
Grease an ovenproof dish (1.25 litre capacity). Add rice pudding and cherries alternately by the spoonful. Spread butter in flakes on top. In a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see
manufacturer) bake for about 20 minutes. Remove and sprinkle with almonds.
