I would increase spice mixture some. Ratio are good. I used Costco 3 pack of organic hamburger. I used 1 kinder and 1 McCormick packet as I didn't have enough chili powder. I 3 timed the ingredients and used Chile powder to make up the difference (18 servings)
I also only had I tube tomato paste so I added 2 to 3 cans tomatoe sauce instead. I decreased the water amount 1.5 cups. This is my preferred. This is for 18 servings
I have made exactly as the recipe call for also and it is good, I think slightly better as above. These notes are for me and my family. I've never had skyline chili so I'm not even a novice when it come to this.
