This is what we need.
There is no garlic and chili pepper in the photo.
If you like spicy, add it. This will also work out very well.
Dry the tofu well and cut into cubes about 3x3x3 cm in size . It is not necessary to granulate strongly.
Cut the onion into feathers.
Mix starch with a small amount of cold water.
If desired, lightly fry the sesame seeds in a dry frying pan.
In a bowl, mix sugar, tomato paste and rice vinegar. (It is rice, it is more tender and sweet, and not a simple 9%! )
You can add finely chopped garlic and chili pepper.
In a wok, heat the oil and fry the tofu pieces in it. Add salt, but without enthusiasm. Fry in parts so that the oil does not cool down, 7-10 minutes until golden brown.
We put the pieces on a napkin.
If the tofu is too soft, the pieces may fall apart (right side of the photo). Not terrible. It just takes less time to fry them, and the dishes will have a less presentable appearance. It does not affect the taste.
In a clean wok, heat sesame oil (without sesame - take a simple vegetable refined). Add the prepared sauce, stirring constantly, bring to a boil, let the sugar completely dissolve.
Add the fried tofu. Mix well so that the sauce covers all the pieces.
Add soy sauce and hot water. Heat up a little and pour in the starch solution, after mixing it. Gradually add the starch, stirring the tofu all the time. Do not add all the starch at once, the sauce will start to thicken and should cover every piece of tofu.
Put the tofu on a plate, sprinkle with sesame seeds and green onions.
