This recipe is Nicole’s favorite, which she enjoyed during her latest visit.

4 Cups pinto beans
1 or 2 Tablespoons baking soda
1 onion
1 Tablespoon salt
1 Tablespoon garlic
1 lb. chorizo sausage
Wash beans thoroughly by placing beans in a colander in the sink and running water over it while washing the beans by hand, rinsing through several times, making sure they are completely clean. Soak beans in tall stockpot overnight with baking soda. (It is said that the soda removes some of the gas.) Make sure water covers beans allowing them to still be covered with water after doubling in size during soaking process. In the morning, drain into colander and rinse thoroughly. Pour beans into pot. Add whole onion, salt and garlic. Cover with water. Bring to a boil. Lower heat, simmer and cover with lid. Fry chorizo in pan, separating into small bite-sized pieces. Drain grease and add to beans. Simmer until soft, 3 to 4 hours.

Note: can also add a pound of fried bacon, drained. (Add when you add sausage.)
My favorite is the local Furnari Sausage. They accept orders online and will ship to your home, so if you are not local, you may want to try it!
