Softer tofu which comes in a tube. Available with or without egg added already. (The picture on the left is with egg, hence the yellow color). If you cannot get Thai tube-tofu, substitute with Chinese ‘firm’ tofu (not ‘extra firm’). This will be close enough. Do not use soft Japanese tofu. It’s too soft to pan fry and will crumble into a big mess. Some people dip the sliced pieces in flour before cooking, to give a bit of extra flavor.
Storage: Store tube tofu in the refrigerator. Make sure to eat before the expiration date.
Note: The easiest way to get the tofu out of the tube is to cut the tube with a knife, right down the middle. Then squeeze the tofu out of the tube from the ends.
