If the story begins with the lack of a child, then hunger becomes central. Food often replaces sex in folktales, and witches with some rule-bound delicacy are the fertility specialists of choice, second only to daring the fairies to give you a baby hedgehog, a snow-child, or an infant the size of your thumb. The trouble starts when a childless queen is given specific instructions– eat the white rose for a boy or the red rose for a girl, but not both. Eat the fair flower and not the bitter, black one. Peel both onions before you eat them. Folklorists would group all of these motifs under the number “T511– conception from eating,” with increasingly specific Dewey-Decimal-style numbers for conception from a flower or a fish, from swallowing a pearl or a peppercorn. Inevitably, the queen fails the interdiction, because she forgets the warning, or because the first thing she eats is so delicious she just can’t help it. Without that failure, there would be no story. Interdiction, violation: a rule is broken and the world is changed.
