To prepare lemongrass, trim the top and bottom, remove the tough outer layers, and then bruise or finely chop the tender inner stalk to release its aromatic oils. This allows the flavor to infuse into your soups and curries.
Preparing lemongrass properly is key to extracting its vibrant citrusy flavor. Here's a step-by-step guide:
Trimming: Start by trimming off the top leafy green portion of the lemongrass stalk, usually about two-thirds of the way down. Also, cut off the root end, leaving you with the more tender, bulbous part of the stalk.
Removing Outer Layers: Peel away the tough, dry outer layers until you reach the pale yellow or white inner core. These outer layers are too fibrous to eat and won't release much flavor.
Bruising or Chopping: Now, you have a few options depending on how you want to use the lemongrass:
Bruising: For soups and broths where you want a subtle flavor, bruise the stalk by gently hitting it with the side of a knife or a rolling pin. This releases the aromatic oils without breaking down the fibers. You can then add the whole stalk to your soup and remove it before serving.
Chopping: For curries and dishes where you want a more intense flavor, finely chop the lemongrass. You can use a food processor or a sharp knife to mince it as finely as possible. This allows the lemongrass to fully integrate into the dish.
Adding to Dish: Add the prepared lemongrass to your soup or curry during the cooking process. The longer it simmers, the more flavor it will impart.
Don't discard the trimmed tops and outer layers! Freeze them and add them to homemade vegetable stock for an extra layer of flavor. This is a great way to reduce waste and maximize the use of your lemongrass.
