The most convenient way to use frozen fruit is to thaw the fruit first. You can use any of the thawed liquid from the fruit instead of water in the recipe. Alternatively, use frozen fruit but add an extra 150 ml water. Also increase the cooking time by about 5 to 10 minutes, but check after an additional 5 minutes cooking to see if the preserve is cooked enough. It is normal when preparing frozen fruits for the paddle to stop turning for a while, but the fruit soon thaws and the paddle will turn freely again.
The minimum quantity of fruit that can be prepared is 500g, otherwise the contents could burn. In the recipe book most recipes use 1 kg of fruit, and can be reduced by half, the cooking time would need to be reduced by about 5 to 10 minutes.
