2. Pay attention when choosing tomatoes. Try to choose tomatoes with pink color and white skin, which feel light, thin and elastic, and the fruit stalks are deep and full. This kind of tomato is full of meat, less gluten and more juice, which is especially delicious when fried. Try not to choose tomatoes that are particularly hard to touch and feel heavy and angular in your hand. After such tomatoes are cut, even the core inside is hard, and the juice is particularly small, and the fried tomatoes naturally taste bad.
