exact text as granted — not AI-modified

I claim:

1. A cookware lid comprising a handle knob having a base and an upstanding handle portion, a first aperture extending through said handle portion and said base, means to mount said handle knob to said cookware lid, said base having a second aperture mating with an aperture in said cookware lid where pressure built during the heating of a cookware will cause a whistling sound through said second aperture, said handle portion having a top surface with a molded depression receiving a thermometer having a probe which extends through said first aperture and an aligned opening in said cookware lid, said thermometer probe extends into a cookware to penetrate half way into a piece of food, where the internal temperature of the food is measured.
