If flower use in pancakes follows the practice when making dandelion wine you need to separate the flower petals before use. You don't want the green bracts (sometimes called sepals) which hold the petals together, as they are bitter and nasty.
BTW I thought gnu's plants were hawkweed rather than dandelion? I have no info on their consumption if so. Similarly leenia's "weak plant that tastes like weeds" (I paraphrase) leads me to wonder whether we are all discussing the same stuff? Wikipedia gives a number of plants that might possibly be taken for dandelion.
