It might not be one of our usual storage solutions, but we just love this set of 4 brightly coloured silicone classic ice lolly moulds.
Simply fill with pureed fruit, yogurt, fruit juice etc, pop the lid on and place in freezer and a few hours later you'll have a tasty treat the kids will love with no hidden nasties.
Better still, as the cases are crafted from silicone you can simply wash and reuse.
