Fennel seeds I've found unpleasant in everything I've ever tried them in. I can't use coriander (cilantro) because Mrs Steve sez it tastes like Fairy Liquid though I love it. That has a serious effect on my guacamole but I've found that I can use fresh parsley to advantage instead. I find the inclusion of orange peel or zest very odd in savoury dishes and I won't use it. I'm thinking of my chorizo and cannellini bean Spanish stew (which is supposed to have both orange rind and fennel seeds, though not in mine) and my Elizabeth David boeuf en daube. I don't miss it.
