Step 1

Add all the liquids to the crockpot and stir

Step 2

Mix in garlic, salt, pepper and butter

Step 3

Add shrimp, clams, corn, potatoes, celery and carrots

Step 4

Cook on high for 4-5 hours (6-8 hours low) or until potatoes and celery are soft

Step 5

The last 30 minutes or once chowder is done, use corn starch and water to thicken the broth if desired. I didn't have corn starch so I mixed 1/2 cup flour with 1 cup warm water and thickened broth slightly buy slowly pouring flour mixture into crock pot. I prefer corn starch but flour will do the trick as well. Follow the directions on the corn starch box to get the thickness you desire.
