Boiling refers to one elementary method of cooking that has multiple purposes. Whereas boiling to make tea means the hot water extracts maximum flavor and aroma from the leaves, resulting in a decent cup of tea. Boiling, too, means cooking pasta; boiling water softens and flavors the noodles. Boiling would also be instrumental in sterilizing cutlery and baby bottles since it would kill the bad bacteria, etc. One would mention various cultures using boiling in soups, stews, and, among others, some desserts.Hope this helps ☺️
