Ok, I know making adult beverages doesn't really count as "cooking", but this is a recipe I modified and love. The original was from The Ultimate A-To-Z Bar Guide by Sharon Tyler Herbst and Ron Herbst. This cocktail recipe book is so fun! It has zillions of recipes, advice on all the proper barware and glasses to use for each drink, toasts, and witty drinking quotes. I modified this recipe to be weaker, because I'm kind of lame with drinking hard liquor. Make it stronger if it suits you.
juice of one large lemon
1 T. sugar
1/4 c. vodka
2 ice cubes
Put the ingredients in a cocktail shaker and shake like mad to try to dissolve the sugar. Strain it out into a cocktail glass (think martini glass), leaving the ice behind. Yum!
