Iced Lemongrass Tea

Preparation

1. Step 1

   Trim off bottom 6 inches of lemongrass stalks. Cut enough lemongrass tops crosswise into 1/2-inch pieces (discard any discolored parts) to measure 1 cup. Bring lemongrass pieces, sugar, and 2 cups water to a boil in a 2-quart heavy saucepan, stirring until sugar is dissolved, then remove from heat and let steep, partially covered, 20 minutes.

   Step 2

   Put remaining 6 cups water in a pitcher. Blend lemongrass mixture in a blender until lemongrass is finely chopped (use caution when blending hot liquids), then pour through a fine-mesh sieve into water in pitcher, discarding solids. Serve over ice.
