This is scary for us because my daughter has life threatening nut allergies and some of the companies are rumored to be adding nut based oils to their olive oils. We've been using Philipo Berio who told me theirs is pure 100% olive oil but I'm going to switch to California Olive Ranch. If you email them with questions (I had to ask about allergens) they will send you recipes and coupons. I got three $1 off coupons.
