Spanish black sausage is similar to the French Boudin Noir but it has a coarser texture, it is worthwhile hunting down the Spanish variety if you can otherwise go for the French variety. This stew, while a great winter dish, also works well in warmer weather by making a lighter version using fresh broad beans. Also, it is a dish that is delicious served cold with lots of mint and a fresh slices of bread and salad leaves. The mint gives the dish a lift lightening and complementing the stew.
