You can just use a can of black beans in any recipe. A bag of dried beans is usually very cheap. I purchased 2.5kg of them for just £6.73. That works out at around 172g per single cup (210ml) of beans.
I tend to use single cups, it costs me 47p per cup.
Once soaked in water overnight, and boiled we receive three cups of beans (630ml) approx.
