It's scary, it's hard, it takes forever.............NOT.

What you need -
2 tablespoons butter
1/2 medium onion, finely diced
1 celery stalk, finely diced
(.5 onion, .5 celery,, you know the drill)

1 tablespoon all-purpose flour
1 tsp minced garlic (optional)
1 (10-ounce) can chopped clams drained
a bunch of
2% or whole milk (doesn't matter don't try with skim)
2 Red potatoes, cut into 1/2- inch cubes
Kosher salt and freshly ground black pepper
What you do -
Boil the potatoes separately in a pot large enough to hold the potatoes and enough water to make them float. (if they floated

)
Saute the onion and celery in the butter until soft and then add the flower to make a lumpy paste.
Add milk and increase the heat to thicken the mixture (add milk slowly until you reach the thickness that you want)
Once the potatoes are done, drain them, toss them in and reduce the heat.
Add garlic if desired, kosher salt and pepper to taste (a bit on the salty side is good)(and lots of black pepper is good too

)
Last but not least, add the clams.
(Note: if you happen to have access to fresh clams, steam them in as little water as you can, just until they open. Shuck them and then dice them up however you want. You will want about 1/2 cup. Still, add them last and only cook until hot.)
This will make about 4 servings so adjust if you need more.
I have done this many times and it is always a hit!
Good Luck.
