For those of you who have not used this before, it is one of the most amazing products in the world. I use this and only this when cooking. I never use any other oil in my cooking. With there being such a range of Frylight oils, sunflower, olive, butter and chilli, just to name a few. PIC What is the FryLight Range? If you’ve not heard about FryLight, Frylight is the original 1 cal (calorie) cooking spray. FryLight is used instead of olive, sunflower, vegetable or even rapeseed oil.
