Mix flour/arrowroot and dry spices (chili powder through cinnamon) and set aside.
Heat olive oil in pan over medium heat until hot and tiny bubbles begin to form.
Add flour/arrowroot-spice mixture to hot oil and cook for 1-2 minutes, whisking continuously.
Remove from heat and slowly add tomato paste, then broth, whisking until smooth. Heat a few more minutes, stirring often, until sauce thickens slightly. Set aside to cool.
