Render the bacon in a dutch oven on medium-high heat. Once it starts to give off its fat, add the butter and let that melt.
Add the onions and let them begin to soften.
Incorporate the flour, Old Bay, and dried thyme and whisk continuously for a few minutes to cook out any raw flour taste.
Continue to whisk and add in the white wine, clam juice, and chicken broth.
Add in the carrots, celery, and potato and bring this to a simmer. Continue to simmer until the veggies are tender - about 10-15 minutes. Taste for salt here and determine if you want to add any.
Once the veggies are nice and soft, add in the scallops, shrimp, and clams along with the corn. Cook until the scallops and shrimp are just done.
In goes the heavy cream and cook until its just warmed through.
Finish with fresh parsley, fresh ground pepper, and flaky sea salt. And, don't forget a piece of crusty bread!
Notes
A word about chicken broth, clam juice, and salt. You will probably use a different chicken broth and clam juice than me. That means the salt content may be vastly different. As with all of my recipes, I suggest adding the salt in layers and tasting as you go along. Just remember that you can always add it, but you can never take it out.
