Grilled Tamarind Prawns

Grilled Tamarind Prawns with Nam Pla Prik

One of my all time favorite food experiences occurred during a trip to Thailand a few years back. We were staying on the island of Koh Samui and spending a day wandering along some of the beaches when we came across a small restaurant with incredible fresh seafood. The standout dish was tamarind prawns - large head on prawns with a delicious sweet-sour tamarind sauce and garnish of cilantro and fried shallot.

After our trip I searched long and hard for a "tamarind prawn" recipe in an attempt to recreate the dish at home. After a couple years of searching and experimentation I developed the following recipe for delicious Grilled Tamarind Prawns. The recipe below includes insights gathered from a few recipes I found scattered across the web. Which websites and what insights came from each has been lost to time, since I apparently never bookmarked any of them! In any case, these prawns definitely remind me of the ones we had in Thailand that day on the beach.

My version of Grilled Tamarind prawns marinates and glazes the prawns with a sweet-sour tamarind, palm sugar, and fish sauce based sauce, accented with a little garlic and a healthy punch of ginger. Cooked over very high heat, preferably on a charcoal grill, the prawns pick up smoky flavors before a sprinkling of cilantro and fried shallot and a squeeze of lime adds crunch and brightness. Serve the prawns with Nam Pla Prik on the side to counterbalance the sour-sweet glaze with the irresistible spicy-sour of the famous Thai condiment and you will have a showstopping appetizer that is hard to beat. These prawns are the "chicken wings of the sea" - tender, saucy, and just messy enough to require finger-licking!

For those who might be hesitant to work with head on prawns, here is some advice: buy the freshest you can from a reputable supplier. If you have access to fresh spot prawns, I highly recommend them for this dish. Despite the head being attached, you don't need to go all "Anthony Bourdain" on them and suck on it if you don't want to. If the prawn heads still have you avoiding this recipe, feel free to use shell on, headless large prawns.

Servings: 4 or more as an appetizer

Time: 60 minutes

Equipment:

• wood skewers (one per shrimp)
• 9"x13" or 8"x10" dish with sides for marinating prawns
• a very hot grill, preferably charcoal

Ingredients:

• 8 large fresh prawns with heads on (U-15 to U-12 size)
• ¼ cup fish sauce
• ¼ cup palm sugar, grated
• ¼ cup tamarind juice (2 Tbsp tamarind concentrate plus 2 Tbsp water)
• 1 tsp soy sauce
• 2 cloves garlic, minced
• 1 inch piece of ginger, julienned thinly
• a pinch of white pepper
• 2 Tbsp cilantro, leaves and tender stems, rough chopped
• 2 Tbsp fried shallot
• 1 lime
• Nam Pla Prik
• 1 small shallot is about 1 Tbsp shallot. I minced the shallot.
• use at least 4 Thai chiles and as many as you like

Directions:

Prepare the prawns:

1. Devein each prawn using kitchen shears and the tip of a skewer. Using shears, make a cut along the back of the prawn from just below the head down to the tail to split the shell and expose the dark colored digestive tract of the prawn. Pull or scrape the tract out using a knife, scissor tip, or the tip of a skewer.
   
   
2. Skewer each prawn from tail to head with a single wood skewer. The skewer is inserted through the back of the tail until the tip is just into the head of the prawn. This prevents the prawn from curling during cooking. Place skewered prawns into the marinating dish.
   
   
3. If using headless prawns, the tip of the skewer should just stick out the head end of the prawn's body.

Prepare the marinade and glaze:

1. Mix the marinade ingredients in a small bowl. Pour half of the marinade on the prawns and set the other half aside. Rotate the prawn skewers to coat each prawn with marinade. Marinate prawns for 30 to 60 minutes, rotating prawns to recoat a couple times.
   
   
2. Make the glaze. Add a little neutral oil to a small saucepot over medium heat. Add garlic and ginger then cook until fragrant, a minute or two. Add reserved half of marinade to pot along with a pinch of ground white pepper then simmer to create a sticky glaze. The glaze should be thickened but still easily pourable.

After prawns start marinating, prepare your grill:

1. Prepare a grill for very high heat cooking. On a charcoal grill this means that you should barely (or not) be able to hold your hand a few inches over the grate above the coals for one second.
   
   
2. Exactly when you start preheating your grill will depend on what type of grill you have! The marinating time does not need to be exact, but I recommend no more than 60 minutes if possible.

Grill and garnish:

1. Grill the prawns over direct, very high heat for 30 seconds per side until just done. The prawns should just be opaque, although this will be hard to see until they are peeled. I suggest cooking one or two at a time first until you are comfortable judging when they are perfectly cooked.
   
   
2. Transfer prawns to a serving platter and pour the glaze over top. Garnish with fresh chopped cilantro, fried shallot, and lime wedges on the side. Serve with Nam Pla Prik as a dipping sauce.

Enjoy! (aka, how to eat):

1. For each prawn, wiggle the skewer while pulling the prawn to slide it off. Twist the head off the body to remove, and give it a suck if desired. You can also give the prawn legs a suck as they tend to trap the glaze and garnishes.
   
   
2. Peel the shell off the prawn body, give the meat a dip into the Nam Pla Prik, a swipe through the glaze on the plate, or both and enjoy!
   
   
3. Rinse (lick your fingers) and repeat!

Notes:

• 1 to 2 prawns makes a great appetizer. 3 to 4 (or more...I ate all 8) is enough for an entrée portion. Perhaps serve with sticky rice and some of your other favorite Thai dishes. 
• This recipe can easily be doubled (or beyond). Simply skewer more prawns and make more marinade.
• Overcooked prawns are tough, chewy, and kind of rubbery, and must be avoided at all costs. Thus, to get both a little charred and smoky flavor without overcooking your grill needs to be very hot.
