Cut the daikon into 4 thick slices that are 3 cm (1 1/4 in) thick each. Cut shallow criss-cross pattern on both sides of the slices.

Put the daikon slices on a rack and let it dry out for a few hours or overnight (it helps it fry better, but if you don't have time, you can still make it!)

Mix the sauce ingredients in a small bowl and set aside.

In a big frying pan that has a lid, heat the oil on medium and fry both sides of the daikon slices until it has a nice brown color. It will take a couple minute for each side.

When both sides are browned, pour in the sauce mix in the frying pan and put on the lid. Let it cook for 3-4 minutes (the sauce should be boiling).

Take off the lid and let the rest of the sauce boil away almost completely - it can take a few minutes. Flip the daikon over 1-3 times so both sides get covered in sauce.

When the sauce is almost gone, keep checking the pan so it doesn't burn. Turn off heat and try to spread the thickened sauce on the daikon if there's any left. You're all done!!
