Fresh lotus seeds are sweet and soft, especially loved to eat, and you have to buy a few pounds a year to save.
Pick a lotus seed that is slightly darker (older, softer), and the general traders will help cut the shell and peel it off easily.
Strip the outer casing and keep it dry and not get water.
Use a knife to gently pry open along the gap between the lotus seeds and remove the lotus core.
Put the peeled lotus seeds in a fresh-keeping bag or a crisper (I am used to using a small sealed bag, take a small bag each time), put it in the refrigerator for free storage, do not need to thaw when you eat, rinse with water and cook directly.
Peeled lotus core to dry, drink water, heat and reduce fire.
