My great-grandmother's chili by Ali Star from the Indian Health Service

 1 pkg. chili tepins (1/4 oz.)
 oregano to taste
 1/2 to 1 head of garlic, crushed
 1 8-oz. can tomato sauce

 You will need a molcajete (stone grinding bowl) for this.
 Grind chili tepins and oregano in molcajete, add garlic, grind it all
 together. Then add tomato sauce and grind some more.

 pretty hot. But I sometimes put two packages of tepins in.
