Okay, so this is my idea: You could make snow cones in the game by putting a snowball, a stick, sugar, and a dye into a crafting table. It would replenish 1 hunger point and give you a small effect depending on the dye you used. I think this would be a good idea because it would give players a good way to get food in snowy biomes, and it would make snow more useful in the game.
I think what the dye should do is change the color of the snow cone, and maybe also the flavor. For example, if you used red dye, the item would be labeled "cherry snowcone", yellow would be "lemon snowcone", etc.
Not sure what black and gray would be flavored, though.
