1, maybe your eggplant is too old.

Another thing is that the soy sauce you use to cook eggplant is not good.

3. Then you put the sugar too early and burned it in it for too long, so the eggplant made is not very delicious and even a little bitter!

4, cooked eggplant will be bitter because the eggplant skin is too thick, it can also be said that the eggplant you bought is a bit old.

If the old eggplant is fried or fried, it must be peeled. If you don't peel it, the skin of the old eggplant will become hard because of frying or frying, and it will be astringent and even bitter. Pay attention to control the heat when peeling. If it is overcooked, it will rot.
