Cheer the Herring!
With the approach of Christmas the variety of piscatorial delights at the Reading Terminal Market's fishmongers expands. New today were herring (sardines) and spearlings, both $4.99/pound at John Yi.
I'll pick up some of those herrings (head-on whole, ungutted but scaled) on my next trip. They are probably fated for a quick pan-fry, with those I don't eat immediately destined to marinating in a vinegar brine with onions, then consumed with rye bread slathered with copious amounts of butter, and Aquavit.
