Step 1

Slice the tofu crosswise into scant 1/ 2-inch slabs, then cut each slab into 2 triangles. Blot with paper towels.

Step 2

Heat a large cast-iron or nonstick skillet and add the oil. When hot, add the tofu and fry over medium-high heat until golden. Turn and cook on the second side.

Step 3

Meanwhile, combine all the ingredients for the sauce in a small food processor and puree until smooth. Taste for salt and add a little extra, if needed.

Step 4

When the tofu is done, pour in half the sauce and cook until bubbling and partially reduced.

Step 5

Turn off the heat, scatter the scallions and sesame seeds over the top, and bring to the table.
