While the product is delicious, it's annoying that the peanut butter stays on the waxy paper instead of on the product. You need a fork to scrape the peanut butter off the protective top sheet.

This product has a strong after-taste of Crayola crayons!  I am in the process of trying different brands of coconut oils for cooking purposes.  Upon opening the plastic container, the aroma of crayons immediately fills the room, and this flavor permeates the food that is cooked in it.  I suspect the source of the problem is the plastic used in the plastic container as I have not experienced this with any of the other brands purchased.  To date, my favorite coconut oil is distributed by Barleans.  The flavor is fantastic.  However, they do not supply a gallon-sized tub,and Dr. Mercola has the best product in that size category.

It has a nice strong flavor with no bitterness.  How strong is it? I would say it is similar in strength to auto-drip using 1 rounded tablespoon of coffee per 8oz of water.
