Consulting my phrasebook I chanced upon this translation of the word 'haggis' under the food and drink section:
plato escoces a base de higado y corazon de cordero, avena y otros condimentos, hervidos en una bolsa formada por el estomago de animal.
So, something to bear in mind if you ever go to a restaurant and fancy ordering one.
A Scottish dish based on lamb's liver and heart, oats and other seasonings, boiled in a bag made from the animal's stomach.
'Haggis' is so much easier to say.
