Bring beans to boil for 10 minutes (doing both tends to make mushy beans)
Scald salt pork with boiling water while beans are boiling, set aside
Remove beans from heat, add 2 tablespoons baking soda to beans in water, stir and wait for foam to stop
Drain (reserving about 4 cups of the water) and rinse beans thoroughly
Preheat oen to 275F
In large (4.5 quart) bean pot put salt pork and onion (whole)
Add beans
Add brown sugar, mustard, salt, pepper, clove, molasses, and catsup
Add approximately 4-6 cups water (including the reserved bean water) to cover beans
Cook in oven for 8 hours at 275F
Notes
Scaling the recipe by 50% works well
Back in 2014 the LA Times posted an article explaining why you don't need to (and probably shouldn't) pre-soak your beans
1 teaspoon salt/lb of beans is generally recommended. Your tastebuds will thank you.
Most importantly, baked beans are always better the next day (or after they've completely cooled)! This really gives them the time needed for all the flavors to soak in.
