This Ecuadorian soup is typically served at Easter, and is ideal for a crowd. Traditionally 12 varieties of bean are used, representing the apostles, but use any mix you like, and whatever vegetables are in season. Look for salt cod that isn't too dry - a thick fillet or side is best. Very dry fish take more soaking.
Achiote or annatto paste, made from the seeds of the annatto tree, is available online from Fireworks Foods (fireworksfoods.com.au).
