You don't need to add it. Mashed potatoes can be made into pancakes without flour, because potatoes themselves contain starch and can also be condensed into cakes.

Mashed potato pancakes:

Ingredients: potatoes, 2 red peppers, 2g water, 50ml.

Seasoning: salt 1/4 teaspoons (about 1 g), light soy sauce 2 teaspoons (10ml), sugar 1/2 teaspoons (about 3g), vinegar 1 teaspoon (5ml).

Practice:

1) peeled potatoes are cut into filaments, steamed and stirred into mud, and red peppers are cut into small circles for use.

2) Add salt to the chopped mashed potatoes, pour in clear water and mix well to make a paste.

3) Pour the oil into the pan and heat it with high fire. When the oil is 40% hot, scoop a tablespoon of mashed potato paste, flatten it with a shovel, and fry it with medium and small fire. Press the red pepper ring on the surface of the pancake. When the bottom becomes hard, turn over and continue frying for 2 minutes.

4) Mix soy sauce, sugar and vinegar into dipping sauce. Just eat the cooked potato pancakes with dipping sauce.

Mashed Potato, also known as mashed potato, is a kind of food made by taking potatoes as raw materials, adding some corresponding seasonings, cooking them in a container, and mashing them with tools, or peeling and mashing them first, then adding other auxiliary materials and stirring them evenly. Mashed potatoes are popular in western food, which endows mashed potatoes with a brand-new taste, which is not only more fragrant, smooth and soft, but also rich in content, which is more suitable for children's preferences and tastes.
