Who doesn't love a hot bowl of spicy chili on a cold winter day? Actually, this chili is good any time at all.
The heat in this chili is provided by cayenne pepper so if you want to adjust the spiciness just add or subtract the amount of cayenne pepper.
Be aware that cayenne pepper is very fiery so it is easy to overdo the spiciness. Just taste as you add cayenne pepper so you do not get it too spicy.
