Instructions
Grind the Peanuts
Add the dry-roasted peanuts to a spice grinder or food processor and pulse in short 1-second bursts, 10 to 15 times. You're looking for a coarse, dry powder that holds its shape when you pinch it. Stop the moment it starts clumping — that's the edge of peanut butter and you don't want to cross it.
Make the Yaji
Combine the ground peanuts with the smoked paprika, cayenne, ground ginger, garlic powder, onion powder, white pepper, ground cloves, bouillon powder, and salt. Mix until evenly combined. Taste a pinch - it should be nutty, hot, and savory with a faint floral heat from the cloves. Set aside 3 tablespoons for the post-grill coat.
Slice the Beef
Cut the top sirloin against the grain into long, flat strips about ⅛ inch thick. Pat dry with paper towels.
Preheat grill to high (450°F to 500°F) and soak wooden skewers for at least 20 minutes before grilling.
Coat and Marinate
Toss the beef strips with neutral oil, then press into the Yaji, coating every surface. Cover and refrigerate at least 1 hour. Overnight is better.
Thread the Skewers
Thread each strip lengthwise onto a flat metal skewer.
Grill
Grill skewers over direct heat, flipping as needed, for 2 to 4 minutes per side until deeply charred at the edges and cooked through.
Second Coat
The moment the skewers come off the grill, dust the reserved Yaji over the hot meat. The residual heat blooms the spices into an aromatic crust. Do not skip this step.
Serve
Serve immediately with shaved red onion, sliced tomato, and lime wedges. Wrap in newspaper for the street food experience, or scoop into a warm tortilla.
Notes
Partial freeze trick: Freeze beef 20 to 30 minutes before slicing for cleaner, thinner cuts.
Oil press is essential: Skipping it results in a greasy rub that slides rather than crusts.
Extra Yaji stores in an airtight jar at room temperature for up to 3 months. Excellent on lamb chops and chicken thighs.
Oven method: Broil at 425°F on a wire rack, 5 to 7 minutes per side. Apply second Yaji coat immediately out of the oven.
