Chili sauce turns sour, which means it has gone bad and can't be eaten any more.

Solution:

1, too much salt will not turn sour. Adding more salt to make fresh Chili sauce can prevent fresh Chili sauce from turning sour easily. Two Jin of red pepper needs about 120g of salt. You can put more salt, but don't put less.

2, 2-3 days don't open the lid at will, it will make the moisture or bacteria in the air enter the fresh Chili sauce, which may make the pepper rot. Fresh Chili sauce usually takes 3 days to finish.

3. Don't use tools dipped in water or oil to make fresh Chili sauce. Whether you scoop fresh Chili sauce with a spoon or chopsticks, don't get wet with water and oil. Scoop it out with clean tools, so it can be kept for a longer time.
