Thought the black food trend that gained all that traction after the Burger King Black Burger and their Halloween Whopper was gone? Wrong. Black ice cream, pizza crust, black lemonade and plenty of other foods as dark as your soul are here in a big way, and they’re probably not going anywhere in the near future. The secret to those deliciously dark treats usually boils down to the addition of activated charcoal (aka activated carbon) for its incredibly dark coloring. When it comes to black lemonade, it’s a sure fire way to freak out your friends or spice up a party. Check out the full recipe Instructables, but it’s basically as easy as adding activated charcoal to your lemonade. The effect is certainly cool, but keep in mind that it can interfere with some medicines, so make sure you educate yourself and your guests before you put out an all black everything spread.
