Tip : If you have a lot of oil left out from frying (for a party, a puja etc), store it in a pet bottle and use it for lighting diyas in front of God. In the initial days of my friendship with net, I used to search for kitchen tips and save them in a file !!! No, even then I wasn't a kitchen person. May be lack of awareness was the reason. I did not know that there are million better ways, to kill time on use net. The second part of the title, is because mom (may be even my spouse) would be outraged. Is it not sacrilageous to use used oil for God!! Won't he(God), be unhappy with me? But my opinion is, no he will not be. First of all, he won't be bothered. In fact he will be glad that, atleast I did light some diyas for him. And even if he is worried , I can convince him, that this way he can contribute a little bit to recycling and Green revolution. If still he is not happy, I can tell him, no...
