Take a shot for what ails you. These small, tasty, and fun drinks pack a big wallop, and here's the guide to making the right one for the job. Need a little something to get the party started? Then go for that college classic: a wiggly-jiggly, artfully arranged, brightly colored assortment of Jello-O shots. Feeling a little tense? Go to the fridge, grab that pre-chilled, distinctive square bottle of Jagermeister from the freezer. Measure one jiggerful of that mysterious herbal-infused purple potion, and knock back vigorously. Enjoy the feeling of warmth that fills the chest, lightens the head, and makes tension melt away. Plus: concoctions to create a little romantic heat with someone and others powerful enough to blow you away. A key explains whether the recipe is a mood lightener, obliterator, medicinal (designed to give a good swift shock to the system), or an aphrodisiac.
