First of all, choose fresh and full corn, not too tender or too old. After you buy it, peel it by hand, scald it with boiling water, then put it in a big bottle, put some white wine, preferably aged soju, and buy a few small bottles of musk, which are sold in fishing gear shops, and soak it together for half a month. You will smell the fragrance when you open it. If put in water, not only carp can eat, but also crucian carp and grass carp can eat. Now I still have two large bottles of corn kernels, "for more than two years, one bottle will not go bad."

I hope I can help you. Remember to adopt when you are satisfied.
