and spices, although like all Spanish cuisine, ingredients will vary from region to region. Morcilla from Burgos has the reputation for being the best in Spain.
To eat as a tapa or snack, Spaniards generally cut morcilla into thick slices (1 inch or so) and fry it in a bit of olive oil, then eat it with bread. It is also a favorite ingredient in stews and bean dishes, and is placed in the pot with other ingredients to simmer.
