I used to buy dried organic diced dates that were coated with oat flour. That really helped. Better than the oil Kevin mentioned, or a sugar coating which is also common with commercially processed fruit.
As it turns out the pineapple doesn't stick to anything once they are pulled apart.
The raisins turned out to be cranberries. I wondered why they were so tart! Too hard to pull apart from each other without becoming a mess. I am thinking of rolling the clumps in either sugar or powdered sugar, would that work?
I might try taking some clumps out and leaving them on a tray like I do to dehydrate herbs to see if that helps.
