How to Make Beef Satay

Place ginger, garlic, onion, brown sugar, fish sauce, vegetable oil, soy sauce, coriander, cumin, turmeric, and cayenne pepper into a mixing bowl; whisk into a smooth marinade.

Bruise lemon grass by hitting it lightly several times with the back of a large chef's knife; mince the lemon grass and add to the marinade.

Cut beef sirloin into strips about 2 1/2 inches long and 1/8 inch thick.

Thoroughly mix the beef into marinade until all beef strips are completely coated, about 1 minute.

Cover bowl with plastic wrap and marinate in refrigerator for 2 to 4 hours.

Preheat an outdoor grill for high heat and lightly oil the grate.

Remove beef from marinade and shake off excess marinade.

Thread 1/4 the meat onto each metal skewer.

Arrange skewers on the preheated grill and cook until the meat stops sticking to the grill, about 1 to 2 minutes.

Flip skewers over onto other side and cook until meat is well browned and shows grill marks, 2 to 2 1/2 minutes.

Turn onto first side again and cook until meat is still slightly pink, 2 more minutes.

Transfer to a platter and let skewers rest about 2 more minutes before serving.
