General Tso's Shakespeare

We read Macbeth, IV:1 after dinner this evening. To refresh your memory, it reads in part:

Round about the cauldron go;
    In the poison'd entrails throw.
    Toad, that under cold stone
    Days and nights has thirty-one
    Swelter'd venom sleeping got,
    Boil thou first i' the charmed pot.
ALL
    Double, double toil and trouble;
    Fire burn, and cauldron bubble.

Second Witch
    Fillet of a fenny snake,
    In the cauldron boil and bake;
    Eye of newt and toe of frog,
    Wool of bat and tongue of dog,
    Adder's fork and blind-worm's sting,
    Lizard's leg and owlet's wing,
    For a charm of powerful trouble,
    Like a hell-broth boil and bubble.
ALL
    Double, double toil and trouble;
    Fire burn and cauldron bubble.
Third Witch
    Scale of dragon, tooth of wolf,
    Witches' mummy, maw and gulf
    Of the ravin'd salt-sea shark,
    Root of hemlock digg'd i' the dark,
    Liver of blaspheming Jew,
    Gall of goat, and slips of yew
    Silver'd in the moon's eclipse,
    Nose of Turk and Tartar's lips,
    Finger of birth-strangled babe
    Ditch-deliver'd by a drab,
    Make the gruel thick and slab:
    Add thereto a tiger's chaudron,
    For the ingredients of our cauldron. 

Eldest Weed, not a fan of the Chinese take-out, said it sounded like tonight's dinner.
