Oil & Vinegar spray set.
I find this set very handy as I keep it on the bench.
When I need to grease my fry pan, or baking tray, I just grab and spray.
No more using more oil than I need.
The same goes for the white vinegar as I use it to add to the water before I poach eggs to prevent them from sticking to the pan. Now I don't even get out the large container of vinegar, which works so much better.
