2 1/2 lb Top sirloin or top round 1 Roast 3 ts Coriander seeds 1 ts Cumin seeds 1 1/2 ts Sugar 4 ts Thai light soy sauce - aew sai 1 1/2 c Oil DIRECTIONS Slice beef across the grain 2"X 3″ in size and 1/4″ thick. Roast coriander and cumin seeds in a fry pan over low heat until fragrant, cool, and grind coarsely in a mortar or a spice grinder. Combine beef and the rest of the ingredients and marinade 1 hour. Place beef pieces on a cake rack sprayed with Pam and put the rack in a foil lined cookie sheet large enough to catch any liquid dripping from the beef. Place the cookie sheet in a lowest setting oven until the beef pieces are dry to the touch and no liquid seeps out when pressed (between 6-12 hours depending on the oven). Over medium-low heat, heat the oil in a flat-bottomed fry pan and drop the beef in 5-6 pieces at a time. Fry until crispy on the outside and around the edges. Drain on a cake rack over paper towels. Keeps up to 1 week in an airtight container at room temperature. Serve alone or with cooked sticky rice. NOTE: Tenderize beef lightly with a mallet if using other cuts of beef. Be sure to drain the oil well. Any excess may become rancid. Cool beef jerky completely before storing.
