Tips:
-You may need to do this in two batches depending on how big your pan is. Reserve half of the sauce for the other half of the tofu block.
-If you are out of potato stach, use corn starch or all-purpose flour. All-purpose flour will give a nice coating but may not allow the sauce to stick as well as with the starch.
-If you really enjoy the flavor of sesame oil, consider frying in a 1:1 mixture of sesame to olive oil or 100% sesame oil!
