I'm pretty sure that the standard Spanish packet Chorizo (above) is available worldwide, but I'm not quite so sure about these ones below.
They are also Chorizo sausages, but designed for frying or BBQ-ing.
Personally I prefer to fry them as they produce a LOT of oil, and on the BBQ that means big flames.
They are spicy but not overly hot, with that delicious flavour of smoked Paprika. These ones above we ate a couple of nights ago with some maize enriched Taboulé.
If you find them in your local shop (and haven't tried them), buy some! They will make your summers even more summery. Delicious.
