Add all ingredients except for the frying oil in a bowl (wow simple eh?). To mix the tofu in more easily I chop it into small pieces, you can also just crush it in your hands.
Use two spoons to gently mix together until everything is JUST combined (do not overmix, this isn't dumpling filling). The texture should not be too wet; if you think there's too much moisture you can add more flour bit by bit. (If you're unsure, you can fry a little test piece and see if it's crispy enough for you)
Heat up oil on medium high heat in a large flat-bottomed pan. Add enough oil so that the bottom is completely covered. Too little oil and you'll have a hard time developing a crust and it'll take longer.
Use the two spoons to shape little balls. Once the oil is hot (the oil is shimmery but not smoking) add the balls into the pan and press them flat with the spoon to form a patty. Do not overcrowd the pan; cook the patties in batches if needed.
Cook for 5~6 minutes. Flip the patties once one side is golden brown and crispy. Cook for another 3~4 minutes or until completely cooked through.
Enjoy :)
