Did you just deep fry a huge batch of chicken? Or was it fish and chips? Just fries? Whatever it is you now have a lot of oil and you know you can’t just pour that down the drain (pouring down the drain will clog pipes and cause wear, wait for oil to solidify before tossing) so you decided to save the oil and now you’re not sure what to do? Why not turn that oil into something useful, what about soap!
