FAQs
Do I need to soak the dried black beans before cooking?
Soaking is optional with slow cookers since the long cooking time softens the beans thoroughly, but soaking for a few hours can reduce cooking time slightly and improve digestion.
Can I make this soup spicy?
Yes! Add chopped fresh jalapeños or a pinch of cayenne pepper along with the spices for extra heat, adjusting to your taste.
