I have several recipes that call for anchovy paste; I think they're typically vinaigrettes. They don't carry the paste at Trader Joe's so I bought a small can of whole anchovies.
Can I substitute the whole (presumably chopped/smashed/pureed) for paste? I assume I would use the same volume? And for others, can paste be substituted for whole in recipes where the whole anchovy is going to be pureed anyhow?
Oh, and since I'll have leftover anchovies from the can, I assume they will freeze fine for further anchovy paste substitutions?
