The whole process of homemade peanut sprouts requires meticulous care and patience, and the following is a step-by-step detailed operation:
First of all, it is necessary to choose good quality peanut kernels, which should be full and round in their particles. These peanut kernels are soaked in water at room temperature for 12 hours, and if it is in winter, it may take longer to complete the soak due to the lower temperature. To ensure that the peanut kernels absorb enough water, you can soak them in warm water, but make sure that the water temperature is not too high to avoid destroying the nutrients of the peanut kernels.
Next, strain the soaked peanut kernels out of the water and place them in a proper vessel. Cover the utensils with a moist cotton cloth to keep it moist and prevent the peanut kernels from being exposed to the air. After about 24 hours, you can see that the peanut kernels are starting to sprout, revealing small bud tips.
Then, prepare some clean river sand, wash it with water and drain it. Choose a vessel with a height-to-width ratio of 18 cm and spread river sand about 5 cm thick on the bottom of the vessel. Place the sprouted peanut kernels evenly on the sand, and then spread another layer of thick 15 times the size of yellow sand, about 8cm thick. After completing these steps, wait for the peanut sprouts to grow, a process that takes about 5 days.
During these 5 days, you need to keep an eye on the humidity of the river sand in your utensils. If you find that the top layer of sand is dry, you need to spray some water to keep the river sand moist, which is essential for the growth of peanut sprouts.
When the peanut sprouts have grown for 5 days, they are almost ripe and ready to be picked. Be careful not to damage the roots of the peanut sprouts when picking.
Finally, you can cook these delicious peanut sprouts to your taste. They can be used for stir-frying, cold dressing, making soups or shabu-shabu. Peanut sprouts are highly nutritious and rich in protein, vitamins and minerals, making them not only delicious but also good for health.
