The Pool Room I grew up in several years ago was ran by the same guy for 50 years. He had the best Chili and Cheeseburger around, He would make the Chili using Flour as a thickener. I would have loved to had his recipe and just wondered if there was some old school pool room chili recipe's out there
Corn Starch will also thicken Chili, as far a recipes there are so many to be had for free on the web, try, experement, work up your best personal recipe.
My personal guidelines is No Beans, Must have Cumin, Jalapeños + Chili Powder, Red or White Onions, Tomatoes, or Tomotios if you want Green Chili. Beef, Pork or Goat Meat. I love Pork.
One of the best Chilis I had on the road was in Piñon, Colorado. It was Green Chili with Hatch Pepper, Pork, spices, and served with Hot homemade Flour Tortillas.
