Required materials: fresh shrimp, old tofu, peeled corn, cooked carrots, baby dishes.

Specific methods: crush the old tofu, chop the shrimp shell into mud, add some lemon juice to remove the fishy smell, add vegetables and shrimp paste to the tofu, add a tablespoon of starch, stir them all evenly, and knead them into small balls.

Mix the sauce, tomato sauce+soy sauce+starch+water, add the meatballs after low heat, cook for 5 minutes after setting, add the sauce after taking out, and cook for 5 minutes to collect the juice.

Sour and sweet is very appetizing, carrots should be blanched first, and corn should be peeled (or not). Add a little more starch. Be careful that you can knead it into balls. If you are not sure, you can try to cook one first.
