Letter ice cube trays. Great for molding butter and chocolate, too. Also fantastic for baking-oven safe to 500 degrees Farenheit. Made of durable, flexible silicone. Includes three trays, from A to Z. These oddly appealing if gimmicky silicone ice cube trays from Suck UK can be used to make ice, or to freeze jelly or butter for your pancakes as pictured here and whatever else you can think of to make a little fun in the kitchen for the whole family.
