Tips & Tricks: 
Scale, clean and gut.  To butterfly, break head from body and then run thumb down stomach cavity; gut will just come away.  Press open flat on a board and remove bones if desired.  Smaller species can be served whole, but do need to be scaled and gutted.
A serve of sardines is equal to about four sardines.
Cooking Tips: 
An oily fish best suited to grilling, baking or barbecuing.  Brush lightly with olive oil and sprinkle with lemon parsley and black pepper.
