In the end, I cut them up skin and all, and popped them fresh into the food processor with a handful of strawberries. The addition of strawberries ensured the fresh apple did not oxidise and turn brown.
The result: A delicious puree with all the goodness of whole fruit. It was a novelty for my two year old, and a tasty treat for my 7mth old.
After giving a little to my girls, I then cooked the rest of it in a saucepan with a few spoonfuls of sugar. Yum! We are all now enjoying a delicious nutritious fruit treat on our cereal, swirled into yoghurt, and drizzled over ice cream.
