Do we have guide lines on staying true to the recipe? As in "I substituted "this" and "this" etc. and then saying I didn't much like it". I have a real problem with that. If I am thinking about trying a recipe and a essential ingredient is Sherry vinegar and I use Balsamic it isn't going to be even close to what the recipe should taste like. Right? Now I don't mean like using dried oregano for fresh. That isn't straying from the original very far. What does everyone think?
