Ive been using fish sauce to replace anchovy for a long long time
my caesars has a few drops of RB40 now that that's the only one I stock
but Ive been using 3 crab for caesars for over 25 years if not more.
as the 3Crab bottles were large , I decanted into a smaller plastic bottle
and kept the larger bottle in a very safe place.
imagine what would happen to your kitchen or PMobile if you dropped a
a bottle of 3 crab ?
I use RB40 to taste .
