1 tbsp fresh thyme leaves or 8–10 sprigs fresh thyme
1/4cup tomato paste
1/4cup cornstarch
2 tbsp, plus 1/2 cup heavy cream
1 tbsp fresh tarragon
1 tsp kosher salt
1/2 tsp white pepper
Instructions
In a large stock pot, pour two and a half cups of water and the lobsters, cover and steam for 10 minutes, then turn off the heat and allow to cool before taking the lobsters out and removing the meat from the tail and claws.
Set the broth that the lobsters cooked in aside (some moisture is lost in steaming, so you’ll end up with about 2 cups of liquid)
Place the stock pot back on the stove, add the butter and the lobster shells and cook on medium high heat until the lobsters begin to brown slightly. You will notice that the fishy smell begins to disappear
Add the diced onion, garlic, celery and carrots and sauté for two to three minutes or until the vegetables sweat and start to soften
Add the sherry and allow to cook for another two minutes
Add the bay leaves, peppercorn and cooking liquid from steaming the lobsters, bring to a boil and then turn down to a simmer
Add the fish stock and fresh thyme, cover and simmer for one hour
Strain the liquid through a sieve (I place a paper towel inside my sieve to catch any dirt or residue from the lobsters) and place back in the stock pot
Add the tomato paste and whisk
In a small mixing bowl, whisk a couple tablespoons of the heavy cream in with the cornstarch
Add the heavy cream, cornstarch slurry and the tbsp of tarragon to the pot and whisk while you simmer, you will notice it thicken as soon as it starts to bubble
Remove the tarragon, spoon the soup into bowls and top with chopped tarragon and lobster meat
