A recipe for Miller... For those of you who cannot find yeast extract, use soy sauce. Traditionally served with bashet neeps and mashet tatties. Make a sauce of sautéed onions, whiskey, and cream to top the haggis; vegans can use other sauces, soya-cream, nothing at all. NB: if served on Burns Night (25 Jan.), Robert Burns's "Address to a Haggis" must be read before anyone is allowed to eat! That's the rules.
