With a mortar and pestle or food processor, blend the shrimp paste, red pepper flakes, ginger, lemongrass, chile, cilantro and salt into a smooth paste. Transfer to a medium bowl and stir in the coconut milk and oil; the marinade will be the consistency of a wet rub.
In a large pot, bring about 12 cups of water to a boil. Parboil the lobsters, covered, 5 five to 7 minutes.
Remove the lobsters from the pot and plunge into ice water to stop the cooking.
Place the lobsters upside down on a cutting board. Slice in half lengthwise from the tail to the top of the head, leaving the tomalley but removing the lungs. Place the lobsters cut-side up in a large baking dish. Pour the marinade over the lobsters and marinate, covered, in the refrigerator for 2 to 4 hours.
Preheat a grill to medium heat.
Remove the lobsters from the marinade and place shell-side down on the hot grill. Cook the lobsters until heated through, 2 to 3 minutes per side.
Before serving, crack open the claws, and then serve immediately with lemon wedges and the Fennel and Mandarin Salad.
Cut the fennel bulbs in half through the stem, and then slice very thinly. Place in a large bowl and add the mandarin segments and micro herbs.
In a small bowl, combine the lemon juice, soy sauce, honey and garlic. Whisk together while slowly adding the oil. Drizzle half of the dressing over the fennel salad and toss. Taste and add more dressing if needed, and then adjust seasoning with salt and pepper.
Serve garnished with sliced scallions and toasted almonds.
