*You may use fewer anchovies or up to two more – or skip altogether – but they do add excellent flavor that’s not at all fishy. When blended, they also provide an element of emulsification to the sauce. If not using, you will likely wish to add more salt (or start with a little less salt if going heavy on the anchovies).
Prefer a smaller batch? The recipe can easily be halved. In this case, it helps to have a mini processor or chopper, as the smaller amount may not be enough to fully catch in the blade of a standard processor.
