Caulking narrow/deep -- backer rod or not?

I will be silicone caulking the gap between my glass vanity top and the tile above it. The gap is about 1/8" high, but maybe 3/4"=1" deep (tile thickness plus float).

Should I just caulk it and not worry? Should I try to get caulk all
the way in there? Should I put something in there first, and just
caulk the surface? I haven't seen any backer rod that is thin enough to use.
