Both of you are right, because it all depends on personal taste. When it comes to salads, sometimes I like raw, thinly sliced mushrooms and other times, I like a caramelized version, it depends on what's in the salad (other ingredients) and what my mood is. Food is all about mixing flavors, ingredients and personalities so maybe you can make your Mum sauteed mushrooms and keep yours "Raw" or uncooked..............package suggestions are only that, recommendations of the recipes designer or creator, that is what's great about food and cooking is, YOU!!!!!! You are the real designer of what you like and can change it however you like, although the original recipe might taste a bit different! But, who's to know? I know this answer is a 50/50 Political answer, but it's what I really believe, have a great Sunday and enjoy your salads.................
