1 Melt the butter in a saucepan and then add the flour to make a roux. Cook for 10 minutes over medium heat, stirring often, then set aside.
2 In a large pot, heat the oil and saute the potatoes, onion, peppers and celery over medium heat until the potatoes are just barely tender, about 10 minutes, or until the potatoes are cooked.
3 Add the heavy cream, clams, thyme, salt, pepper, tabasco sauce, and roux. Whisk well to blend in the roux.
4 Bring to a boil, then reduce the heat and simmer for about 5 minutes, stirring occasionally. Add more seasoning to taste.
