Well, I don't know if typical Manhattan clam chowder has bacon, but I don't care- having the entire apartment saturated in the smell of bacon most of the day was awesome. ...and almost cruel.
Manhattan clam chowder is different than New England style in that it is tomato/broth based instead of creamy. Here's an easy crock pot recipe! It has a very bacon-y, almost smokey flavor.
3 (8OZ) cans clams, with juice (I used 4 6-something oz cans)
2 14oz cans tomatoes, chopped, with juice
2 oz bacon, diced (I used a whole package of already cooked bacon, 2.3oz)
1lb potatoes, peeled and diced
1 large onion, finely chopped
1 large carrot, thinly sliced
2 stalks celery, thinly sliced
2 tablespoons finely chopped fresh parsley (I used dried)
1/2 cup dry white wine
Salt and fresh ground black pepper
Combine all ingredients in a slow cooker. Season with salt and pepper. Cook on low about 9 hours.
