Most dependable product in my kitchen!

I have been using Hard Oil for several years now and it is best non-food product in my kitchen. Disposing of cooking oil should come with a level of environmental responsibility. Hard Oil allows cooks dispose of cooking oil with little to no mess. Will continue to support The Kitchen Laboratories and this product.

Greatest thing to happen to hot oil ever!!

At first I didnt understand how it worked but I let the oil cool off a bit too much. If you use it right away, it sets it right up to be solid. Can't wait to buy it again when it is in stock

It’s very easy to use .

Bruce M.

I used to save plastic containers with screw on lids just so I could fill them with dirty cooking oil and put them in the garbage without risk of them making a mess. With hard oil I add it to the hot oil let it cool and then slip the whole mess out of the pan and into the garbage. I love this stuff! Thanks!
