Pomace oil is perfect for this application. We even take it a step further and make our own 80/20 blend with it made from 20% pomace oil and 80% canola oil. If cost is an issue, you can also go to 100% canola or some other vegetable oil on the dough balls.On a secondary note, we have found that the dough balls skate around way too much if we put oil in the dough boxes (large plastic, not individual). This can create a situation where if we are not extremely careful when handling the dough boxes, we can end up with all of the dough balls huddled at one end of a box, creating one large dough ball on the following day. We feel that it is better to not oil the box itself, but instead put the dough balls into a dry box, then wipe oil over the tops of the dough balls. A plastic scraper works wel for removing the dough balls from the box.
