I have done it!!!! Grocery store bought fresh basil kept firm and green in the refridgerator for nearly 2 weeks!
I treated the basil much as you would a bouquet of flowers, first I cut the stems, then put them in a plastic (glass would get too cold I think) vase and loosly placed a plastic grocery bag over the "bouquet" making sure there was air flow at the bottom - no lie - my brown thumbed comrades! We no longer have to suffer our basil to ooze form a tube or spill from a jar just cuz we can't grow it fresh!
Of course, I only tried it the once...
