About sauce:
Made with soy sauce, add boiling water, star anise, monosodium glutamate or chicken essence, a little sugar and some other spices, and cook for half an hour. Before eating again, some people pour a little sesame oil, which is available in Sanming, but not in Yong 'an fruit bar.
Regarding peppers, we must use Yong 'an yellow pepper, which is also a specialty of Yong 'an, and this spicy taste is authentic!
I can't say clearly on the internet. It's really like going to find the master of Yong 'an Fruit Bar to study for himself!
