possum, lol!
The chowder is New England style. I've finally got a recipe I can prepare consistently.
It uses both potatoes and a roux to thicken.
You start by grating potatoes and cooking those down, adding liquid, until you have a very thick soup. Add potato chunks and vegetables. Cook until tender. Add a butter roux with milk and some cream. Add the clams and parsley. Of course, I've been seasoning all along (a mixture of peppers and dried herbs).
