Fuzhou-style snacks are rich and varied, among which the pot-side and dialect, also known as "fixed-side paste", have become a special symbol of Fuzhou, and everyone who grew up in Fuzhou or lived in Fuzhou for a long time loves to eat them. Fuzhou people who have left their hometown to live overseas will feel as if they have seen the beautiful scenery of their hometown when they hear the word "fixed edge paste" in a foreign country.

Fixed-edge paste, also called plate-edge paste, is a clear soup made by boiling clams, mushrooms, shrimps, onions, day lilies and ingredients in an iron pot and then igniting them. After the upper part of the iron pan is baked, coat it with peanut oil, then pour the prepared thick rice slurry evenly around the inner edge of the iron pan, dry it, and shovel it into the soup to cook for a while. Just out of the pot, the top edge is white, crisp and thin, the soup is clear and non-sticky, and the food is delicate and smooth, fragrant and delicious.

Almost every household in Fuzhou will make fixed-edge paste. Every time the China Lunar New Year is long in summer, Fuzhou citizens and suburban farmers will make fixed-edge paste to escape the heat. Because the long summer has entered the busy farming season, cooking fixed-edge paste on this day is not only for the whole family to eat well before going to work in the fields, but also for the neighbors to taste together. Just like rinsing the edge paste, "one grain (rinse) is cooked" to connect feelings.
