Blaugh! Anchovies. That's fish bait, not food. Now, sardines from a can on crackers: breakfast!Anchovies "in bulk" could be a bridge too far for me... at least that way. I like using them when they make something rich but you're not sure what made that richness happen. Sort of like how I use fish pastes generally.
You mean mix it into the burger prep? Never tried it... sounds great!
On the other hand, good Vietnamese food requires fish sauce, and also I think Worcestershire sauce. So, maybe fermented pulverized and aged anchovy juice is food?
