This is how I make my creamy tomato soup.
2 Tbs. butter
2 Tbs. Flour
1 Cup Liquid (I use rice milk)
1 sm. Can Tomato Paste
Molasses or honey to taste (this takes the tangy out and helps mellow the acid taste in the tomatoes)

Melt butter in pan. Add Flour, brown on medium while stirring constantly. Slowly add liquid (milk) cook on medium stirring constantly until thick (gravy consistence). Then add tomato paste and sweetener. Stir until hot... if this is to thick add more of the liquid.
