Stone the stone fruit. Then boil the fruit with a little water to make a compote, it only takes a few minutes. Let the compote cool and puree. Possibly sugar.
When the fruits are very ripe, you can puree the compote with very little water, without boiling.
First pour the puree into a dessert glass. Spread about 3 tablespoons of oat soyade on top of the puree. Cover the dessert with the biscuit fragments and serve.
If it is to be prepared several hours before eating, first chill without breaking the biscuits and then apply the biscuits before serving.
If the fruits are sour, you can sweeten the compote a little.
