The lily seed green cinnamon soup

Remember that when the lilies are on the market in the summer, mothers often cook a pot of lily green bean soup, and that the lily tastes bitter, tearing out the thin membrane on the lily petals before cooking, bathing in cold water, removing some of the bitterness, and then cooking with green beans. The lilies now seem to be out of bitterness, making soup and not having the taste of childhood. At one chance, the lily seed was seen, which was said to be bitter and to have been bought back to see if it could be recovered. Don't tell me it's true. It just tastes a little bitter, sweet, a bowl down, and it's nice。
