We're all for throwing new things onto the grill, but we were skeptical of grilled lemonade when we heard about the trend. After trying it, we're sold: Grilling the lemons makes the drink taste caramelized and slightly smoky. To make a pitcher, dip the cut sides of 16 halved lemons in sugar and grill until marked, about 5 minutes; let cool. Simmer 1 1/4 cups sugar with 1 3/4 cups water and a pinch of salt until dissolved; let cool. Squeeze the lemons through a strainer into a pitcher; stir in the sugar syrup, some ice and a few of the grilled lemons.
