A booke of Cookery, 1591

This sounds amazingly simple and good.   Heat up a waterdowned beer then thrown in the shrimp.  Once they've been cooked, throw some salt on them.  I think this one might just be doable.  

I'd also like to look more into the yellow/mustard sauce as this cookbook above also talks about it for fish days.  The one problem with the above book is that it's late period English - meaning they allowed butter and eggs into their fish dishes.   It's easy to take out, but it is something to look for as well when reading the later stuff.   The Catholic Church didn't allow butter and eggs until the 17th Century.
