To add further insult, the bean shown isn't even the correct one. It comes from Leon, which is not Asturias, and the same company markets the correct bean, from Asturias under a different house brand name.
A cassoulet is ALL about the correct bean, so I assume the same thing about fabada. 'Close enough" is not for me. Even if I have to spend 20 bucks for 2 dollars worth of beans. What a country we live in. This is peasant food in Spain...
