I didn't have a ton of tomatoes, but did manage to make this with 8lbs. I used 1-1/2 cups sugar, less than 3/4 T. salt, no celery salt because I didn't have any, 1-1/2 t. onion powder (didn't have onion salt), a dash of pepper, 1 stick and 2-3/4 T. butter and 3/4 cup flour. I was surprised when I tasted i because I didn't actually expect it to have a lot of flavor, but WOW - it's great! I bet my husband will even eat this tomato soup!
