I have mixed oil everyway that has been documented here.
Grapefruit juice is my choice. However tonight I drank it straight from the bottle with out cup or tablespoon. With the typical olive oil top on the glass bottles you can swing it to your mouth and it will shoot to the back of your throat and you dont even taste it. The gross part is holding it in your mouth. So I think the quick chugg from the bottle is a neat way to do it. Just dont fight it or try to hold it- chugg it a few times and its not that bad.
