The method and formula of milk cube are as follows:
Ingredients: 15g of purple potato and 2ml of milk.
auxiliary materials: 35g of starch, 3g of soft sugar and 15g of coconut.
1. First of all, we need to prepare all the ingredients needed to make this small square of coconut milk with purple potatoes: prepare 3 small purple potatoes and 2ml of milk, and weigh 35g of starch, 3g of soft sugar and 15g of coconut milk with a kitchen scale. Peel and wash the purple potato first, then put it on a chopping board and cut it into thin slices with a knife. Put it in a plate and steam it on a steamer until it is tied with chopsticks.
2. Take out the steamed purple sweet potato and put it into a bowl, and crush it into purple sweet potato paste with a spoon. Add milk, starch and soft sugar into the bowl and stir until the starch has no dry powder and the soft sugar is completely melted.
3. Pour the evenly stirred liquid into a small milk pot, and stir while cooking on low heat. Keep stirring with a high-temperature resistant silicone scraper, otherwise the purple potato paste will easily paste the pot. After constant stirring, the original flowing liquid becomes thicker and thicker, and finally it is stirred into a paste, and then the fire can be turned off.
4. Take a fresh-keeping box, spread a layer of fresh-keeping film inside, put the cooled purple potato paste into the fresh-keeping box with a scraper, and gently shake the fresh-keeping box several times to make the surface smooth. Then completely wrap the purple potato paste with plastic wrap, turn it over and put it back in the box, so that both sides will be flat. Cover and refrigerate for 2-3 hours.
5. Take out the refrigerated cubes of purple sweet potato milk, put them on the chopping board, and cut them into cubes with a knife. Put it in a box with coconut milk and roll it around, so that all six sides are covered with coconut milk. Then it can be directly served, and the small square of coconut milk and purple potato milk with soft, sweet and milky flavor is ready.
