If your bacon was frozen, place it in warm water for 10-20 minutes until thawed enough to separate the pieces. Place the bacon in a large hot stock pot and cook each side until crispy (about 2 minutes per side). Remove the bacon once cooked and place on a paper towel for later.
Turn the heat to medium and saute the potatoes, red onion and carrot in the bacon grease for about 5 minutes, stirring occasionally.
Add the garlic and cook for 45 seconds, stirring the entire time.
Now add 1/4 cup of flour and stir to coat. Pour in the milk and stock, and stir well.
Drain the clams and add them to the pot, along with the frozen flounder, frozen raw shrimp and drained canned corn. Stir to combine.
Season with thyme, bay leaf, salt and pepper.
Simmer for 1 hour on medium/low, stirring occasionally. Before serving, taste to see if more salt is needed.
When done, remove from heat and add heavy cream and butter. Remove the bay leaf, sprinkle with parsley and chopped bacon bits and enjoy!
