In a stockpot, peel, cube, and boil potatoes in salted water for approx 20 minutes. Continue below, but when potatoes are finished, drain and cover the pot until you are ready to add the potatoes.
In another stock pot, cook bacon until crisp. Drain, reserving 1 tablespoon drippings. Set bacon aside.
Saute onion and garlic in the drippings until tender.
Stir in flour, salt, basil and pepper; mix well. Gradually add broth. Bring to boil; boil and stir for 2 minutes.
Add the potatoes, half-and-half cream, and hot pepper sauce; heat through but do not boil.
