Chop the peppers and onion kind of big, not too finely cause you want them to have oomph. Fry the peppers and onion in about 1/2 stick of butter till almost tender,it's okay if they have a little bite to em. Add the shrimp straight from the freezer and cook for about 5 minutes. (Note: I made this the other night and actually took the time to thaw the shrimp. This reduces the chance of thinning the sauce too much.).
Put the angel hair in boiling water at this point so it will be ready at the same time as your sauce.
Stir the spoonful of flour into the shrimp and add the half and half. Season to taste with the pepper, garlic, seasoned salt and creole seasoning. I like it with a nice heat. Let the sauce simmer gently for about five more minutes till thickened and Voila!
Make some garlic toast while the sauce is thickening. Dish up your angel hair and spoon the sauce over. OMG -- this is sooooo good!
