I adore EVOO for cooking, for salad dressings, and even homemade mayo (gives it much more robust flavor than a bland oil). Still, I use the less expensive and tasteless light OO for soaping because, well, I'm not eating the soap.Yes, my husband is Romanian and he says most of our (meaning American) olive oil has no flavor so to get "flavor" he only buys EVOO and sometimes pays for the imports, but recently the prices have been more outrageous than before. I usually pick up a gallon because he loves eating tomatoes with feta drizzled with olive oil, even letting it marinate about an hour before eating it. He also prefers i use OO when cooking. So, in order to ensure I have enough to use for soaps AND he has enough to eat with, we buy EVOO by the gallon.
Seriously, even though I don't use that much OO in soap, I still find it worthwhile to buy the light stuff to keep my soaping costs down and get a lighter soap batter, too. To each her own!
