These days, it's hard to find sardines that are both inexpensive and tiny and delicate. Riga Sprats, packed in Latvia and found in many international-style markets, fit the bill nicely.
Lightly smoked and packed in sunflower oil, Riga Sprats are the kind of high-quality delicious little fishies we grew up with. Each tin contains a generous 5.6-ounce portion of fish, carefully laid in layers - ready for lunch, snacking, or canapes and recipes. And they're very inexpensive - the local markets here carry them for $1.79 - $1.99 a can, and you can even find them on Amazon for $1.79 each.
The tiny fish are quite wonderful - scaleless and perfect, mildly fishy and with a hint of smokiness. They're great on crackers with some thinkly-shaved sharp onion and some Turkish beyaz peynir (white farmer's cheese.)
