Answer:
I drive men mad for love of me. Easily beaten, never free.
Large as a mountain, small as a pea, Endlessly swimming in a water-less sea.
Kills the bad ones and the sad ones. Tightens to fit, so one size fits.
They try to beat me, they try in vain. And when I win, I end the pain.
My first is twice in apple but not once in tart. My second is in liver but not in heart. My third is in giant and also in ghost. Whole Iām best when I am roast.
Often cooked as fillet, this meat comes from an animal that swims underwater.
