Sardines are a common ingredient in Thai cooking. Normally we eat them fresh rather than tinner, they are steamed, grilled or deep fried.

Deep Frying
The easiest way to cook them is to deep fry. Heat the oil to 190 degree Celsius, then put the fish into the oil. The moisture in the fish will cause the oil to spit. Listen for the noise to die down (as the water is cooked off) you can remove them. It only takes 2 minutes or so to cook a small fish like this.
