It's too hot. The air is oppressive and sticky, and it just keeps getting hotter... I need a nice, cold glass of lemonade.  Fortunately, I have a bag of lemons and plenty of ice! So now the question becomes one of technique. Keeping in mind that I'm hot (and consequently lazy), is it worth taking the time to zest the lemons before adding sugar and ice, or will the sugar alone suffice to extract those refreshing oils from the rind? 
Use a vegetable peeler to peel of large strips of rind. That way, it'll be easier to remove once you're done steeping. If you don't mind it being mildly alcoholic, steep them in vodka and then strain the vodka into the lemonade.
