Lemongrass Beef

 

1 lb [455 g] top sirloin

2 stalks lemongrass

3 T. fish sauce

1 T. brown sugar

Neutral oil, for cooking (such as canola or avocado)

 

Freeze the beef for 2 hours, so it’s easier to slice thinly. Remove the tough outermost leaves of the lemongrass. Cut off and discard the reedy stalk ends and the bit of root, saving only the tender light green part from the root side (you’ll be left with about 1 1/2 oz [40 g]). Place the tender lemongrass in a food processor and blend until finely chopped. Add the fish sauce and brown sugar to the food processor and blend. Once the beef is firm but not frozen solid, slice very thinly. Spoon the lemongrass mixture over the beef and toss together to evenly coat everything. Let sit for at least 30 minutes in the refrigerator (and for up to 2 days). To sear on the stove, preheat a nonstick saute pan over medium-high heat. Once hot, add about a tsp. of oil, swirl to coat, and add about a sixth of the marinated beef. Spread it out into a single layer (do not crowd the pan). Let sear
