First, yam.
Yam has been the "first nourishing food" in autumn and winter since ancient times, and it is the most seasonal food after beginning of winter. Yam contains a large amount of cassava starch, carbohydrates, various nutrients and nutrient elements, and has strong effects of tonifying kidney and essence, nourishing health, moistening lung, relieving cough and resolving phlegm, tonifying middle energizer and benefiting qi. The key of yam can be divided into two categories: one is waxy yam, which is represented by yam. Cassava has high starch content and low water content, and tastes powdery and waxy. Generally slender, with many fibrous roots on the surface. The other is the common tough yam, which is also called pure yam because there is no fibrous root on the surface. The design is thick and malleable. You can break the number without paying attention to a section of yam. This tough yam has less starch content and more water content.
Waxy yam, also known as iron core yam and iron stick yam, is famous for its scattered rust-colored spots on its surface. This yam is very suitable for instant steaming, especially for some dieters, beautiful women, the elderly and children. It is an excellent choice as an ideal substitute for dinner after cooking. If you can't catch up with cooking in winter morning, you can also steam two yams, which are fragrant and sweet and pleasant. You can also peel the yam, cut it into pieces and cook porridge. The classic Nanjing Jinling specialty snack "Meiling porridge" is cooked with yam as the basic ingredient. This glutinous yam is also the key raw material for making cakes and desserts, such as traditional food sweet-scented osmanthus yam cake and blueberry yam mud. They all use this yam.
And the kind of yam with strong ductility is mainly used for cooking. Fried yam with auricularia auricula or pickled yam with vinegar is a must in meat dishes; Even stir-fried sliced meat is a classic and famous home-cooked dish. There is a classic slippery dish in Anhui cuisine, which takes starch and fresh meat as the main raw material, cuts the diluted egg skin into diamond-shaped thin slices, and adds yam, black fungus and garlic. This is the slippery sliced meat and soup that many people like to put well.
Second, sweet potato.
Speaking of sweet potatoes, many people will suddenly think of baked sweet potatoes in winter. Put a simple baked sweet potato stove on the tricycle, and you can smell the aroma of baked sweet potatoes from a distance. Nowadays, with the popularity of electric ovens in more and more families, more people like to bake sweet potatoes at home. Using small pieces of sweet potato can also maximize the aroma of baked sweet potato outside. When I was a child, I loved to drink sweet potato chips, whole grain porridge, a big bowl of porridge and half a bowl of sweet potato chips, and I couldn't get enough of them.
Although sweet potato is cheap and good, its nutrition is comprehensive and all-round: in addition to the rich variety of sweet potato starch and carbohydrates, the types of vitamins are particularly rich and colorful, including vitamin D, carotene, vitamin C, vitamin B tablets, vitamins and other nutritional elements. Among them, carotene is three times that of carrot; In addition, sweet potato also contains amino acids such as calcium, phosphorus, iron and potassium. It is precisely because of these factors that sweet potato is an idealized staple food rather than food, and it can definitely replace steamed bread, white rice and other meals after instant cooking.
Third, sweet potato.
Sweet potato, also known as taro, has similar nutritional elements to sweet potato; In addition, sweet potato contains more sugar and mucin, which can improve human immunity and disease resistance in winter. Sweet potato is easily absorbed and digested by human body, especially suitable for the elderly and children. The most natural way to eat sweet potatoes is to replace the staple food after cooking, which is fragrant and elegant, and the powder is delicious; If stewed with ribs, chicken breast, etc., it will enhance the delicacy to multiple levels.
