3. Add lily and white fungus, add 1-2 drops of lemon juice, and boil until thick
Tips:The anthocyanin in purple potato turns blue when it meets alkali and turns red when it meets acid. Add two drops of lemon juice to make the color more beautiful. The amount is very small and the sour taste is not tasted.
