We don't have Chamomile Liqueur and have no idea what it tastes like. But since one of the two suggested garnishes is elderflower, we thought we would substitute Elderflower for the Chamomile Liqueur. We can't compare it to the recipe as specified but enjoyed it. And since we had a pork hock in the oven, yes we were anticipating something special. Thanks to our good host for another delightfully elegant creation.
