Step #3 Add the garlic & saute for 2 mins.
Step #4 Reserve.
Step #5 Return the pot to moderate heat & crumble in the beef and pork.
Step #6 Increase the heat to high & brown well, without stirring, for 5 mins.
Step #7 Reduce the heat to moderately-high & brown, stirring every once in awhile, for 15 mins longer.
Step #8 Return the onions to the pot & stir in the 1/2 c of the chili powder, 1 tbsp of the cumin, 2 tbsps of the sugar, 2 tbsps of the cocoa, cayenne, fennel seeds, salt, 1 tbsp of the oregano, & bay leaves.
Step #9 Add the tomatoes & their juices, the tomato sauce, 2 bottles of the beer & 4 c of water.
Step #10 Bring the mixture to a boil over moderate heat.
Step #11 Reduce the heat to low & let simmer, uncovered, for 3 hrs.
Step #12 Stir carefully every 30 mins, but do not stir during the last 15 to 20 mins so all of the fat will rise to the top.
Step #13 Meanwhile, prepare the beans.
Step #14 Put the bacon in a large, heavy saucepan set over moderate heat.
Step #15 Cook, stirring frequently, until crisp & deep golden brown.
Step #16 Spoon off all but 1 tbsp of the fat.

Step #22 remove this from the heat & set aside.
Step #23 When the chili has cooked for 3 hrs, degrease it, skimming off most of the fat.
Step #24 Place a paper towel flat on the surface to soak up any remaining fat repeat, if necessary.
Step #25 stir in the the remaining 1/4 c chili powder, 1 tsp cumin, 1 tbsp cocoa, & 1 tsp oregano.
Step #26 Taste for balance of acidity to sweetness & stir in the the remaining 1 tbsp sugar, if needed.
Step #27 Add the beans & their cooking liquid.
