1. Add more serranos if you like your chili nice and hot! Adding two gives a little heat.
2. Chili usually tastes best the next day because all the spices have had a chance to settle.
3. Go nuts and add some toppings to the chili before eating. I highly recommend topping it with whole fat Greek yogurt.
4. If you don't have any cinnamon sticks handy, one stick equals to 1/2 teaspoon cinnamon.
