It depends upon what you intend for the texture of your cone. The batter baked in the cone softens it a bit it to give almost a stale feel. Baking a cupcake and placing it in the top of the cone keeps the cone crisp.
I know that this is totally not the point but I can't for the life of me figure out another way that meringue could be pronounced. Mer-ing-ay, Me-rang, Mer-ine-ge.. What is it??
