I'm bringing a haggis into work on next Friday, its essentially precooked, got instructions from the butcher to wrap it in foil with a little water and cook it in the oven for about an hour. I was going to cook it the night before, bring it in and heat it in the microwave, but I'm wondering if I could just cook it in the slow cooker instead?
Anyone ever cook your haggis in a slowcooker?

thanks
Dave
