In a large pot, heat the oil. When hot, add in the leeks, and sauté on medium-high heat until leeks are lightly browned, about 8-10 minutes. When cooked, pour in coconut milk, stock, carrots, and celery. Bring liquids to a simmer and add in the spices and lime leaf. Salt and pepper lightly, then cover with lid and allow to simmer on medium low for 10 minutes.
Next, add in butternut squash and continue to simmer for 22 minutes or so. The carrots and celery should be very soft. Taste broth occasionally and add salt and pepper accordingly.
When all ingredients are tender, transfer to a heat safe blender and blend until smooth. Taste if any additional salt is needed.
Set aside until scallops are seared and ready.
FOR SCALLOPS:
Wash and dry the scallops, then season each side with salt and pepper.
In a medium skillet, melt 2 Tbsp of butter on medium-high heat. When butter is hot, place about 5 scallops in the butter—you should hear the sizzle and searing. Allow scallops to sear for 1 ½ minutes, then flip and sear the other side for 1 minute. Do not disturb the scallops when they are searing.
To serve, pour soup into bowls and top with two scallops and any desired garnishes—I used parsley. Enjoy!
