These slow cooked barbecue beans owe their explosive flavor to the fact that they include nearly everything...except the kitchen sink.
Note:If you can not find Chinese BBQ pork in your area you can substitute 3 or 4 slices of bacon. Do not be tempted to speed up the cooking time by increasing the heat. It's the slow cooking that makes these beans so good.
If you prefer you can cook the beans in a pot on the stove top instead of a crock pot. Just cook on low heat and keep the beans covered with water. How to know when they are done? Taste 'em.
A note on liquid smoke. Most liquid smoke contains poly cyclic aromatic hydrocarbons (PAHs), which can be carcinogenic. The amount of PAHs in a teaspoon of liquid smoke is very small but if this concerns you, leave it out. There are a few brands of liquid smoke that do not contain PAHs so check the ingredients label if you want to avoid it.
