I've been pouring my RBO into a clean 2 cup measuring cup (pyrex I got for making soap then learned that glass and lye are not friends), pouring more than I need and just adding whatever extra I poured into my cooking oil bottle. Usually only wind up with an ounce or two to add to my cooking oil. I have not added ROE to my oils (yet- soon as I get some I will, then the excess will go back into the main jug). It pours a lot less drippily if you can pour kind of fast, which you can do into a measuring cup. I may have to try the stick method, though.
