There is only one reason why spinach can't be eaten with tofu: spinach contains a lot of oxalic acid, which will combine with calcium to form insoluble precipitate. However, this statement fails to see another aspect of the problem. Spinach also contains many factors that promote calcium utilization and reduce calcium excretion, including rich potassium and magnesium, as well as vitamin K. As long as the spinach is blanched in boiling water 1 min, more than 80% of oxalic acid can be removed. Blanched spinach will not cause its nutritional loss, and its vitamin K, like carotene, needs oil to help it absorb, so you must remember to put some oil when making spinach tofu stuffing.
After blanching the spinach with water, chop it with a knife (don't chop it too much), and flatten the tofu with a kitchen knife. It is best to put a little egg in this stuffed dumpling, which will taste better. Just put vegetable oil, salt, vegetarian food, thirteen spices and chopped green onion (chopped green onion) as the seasoning.
