Long noodles are mostly served as home meals for entertaining guests. Pay attention to skillful women in rolling out the dough, "roll it into paper, cut it into lines, put it in the pot and turn it around; pick it up in the bowl." Especially the "knife-sliced ??noodles" from Jujia and Lujiayuan are the best. When cooking, the soup is cooked under the front pot and in the back pot. The sauteed soup is meat and the sour soup is vegetarian. Different seasonings give different flavors. Farmer noodles have the characteristics of thin, thin, long, ribbed, light, fried, chewy, sour, spicy and fragrant. Slender noodles are poured with soup, and wide noodles are cooked dry. In the old days, people would eat noodles without drinking soup. Instead, they would pour the noodles back into the pot and pour them over, which is commonly known as "salivating water surface". After liberation, women's hand-rolled noodles were gradually replaced by machines. There are more vegetables to accompany the soup, and the old habit of eating noodles without drinking soup can be changed. Generally, when entertaining guests in a farmhouse, besides wine and meat, the staple food is noodles or steamed buns. All kinds of pasta are so delicious and fragrant that you will never get tired of eating them.
