Melt bacon grease in a skillet over med-high heat. Put flour into a paper bag and shake the meat with the flour to coat meat. Add the meat to the bacon grease a little at a time and brown well & evenly.
Remove the meat to a 5 quart Dutch oven. Add the onions & garlic to the skillet and sauté until translucent. Add these to the pork in the pot. Stir in the remaining ingredients, bring pot to a boil, and keep stirring every 2-3 minutes.
When boiling lower heat to low & simmer for 45 minutes. Taste, adjust seasonings as per personal taste, & cook for 30 minutes or more.
