Well if you don't like oatmeal you can get a gluten free haggis from a butcher in huntly, the barley and oatmeal is replaced with rice and lentels. The wife and i were at a burns dinner dance for the ceoliac society at the beach ballroom on friday and the haggis was great.
You can contact the butcher here Forbes Raeburn & Sons, 7 Bogie Street, Huntly 01466 792818
