Directions

1. Cut off tip of each cob. Stand corn in a wide shallow bowl; using a sharp knife, slice downward to release kernels. Scrape length of each cob with a spoon to release pulp. Discard cobs.
   
2. In a large saucepan, cook bacon over medium-high until crisp and browned, 4 to 6 minutes. With a slotted spoon, transfer bacon to paper towels.
3. Add scallion whites and potatoes to pan; cook, stirring, until scallions have softened, 1 to 3 minutes. Add flour and cook, stirring, 1 minute. Add milk, seafood seasoning, thyme, and 2 cups water.
4. Bring to a boil; reduce to a simmer and cook, stirring occasionally, until potatoes are tender, 10 to 12 minutes. Add corn, shrimp, and scallion greens. Cook until shrimp are just opaque, 2 to 3 minutes. Season chowder with salt and pepper. Serve topped with bacon, with crackers alongside if desired.
