The dish is prepared by first soaking the eggs in the urine of young boys, then the mixture is heated over a stove. After boiling, the entire surface of the egg shells are cracked, and they are placed back into the urine. The used urine is then replaced with fresh urine and the process is repeated. The soaking process
cures the eggs in the urine, and the entire process generally takes a full day. Virgin boy eggs are similar to
century eggs in their curing process and historical roots, although century eggs have become much more popular and do not use urine. ==Modern culture==
