I have made the pastry gluten free as I have coeliacs disease. It's taken me along time to perfect, but now although theres many different ingredients to the Irish original, it tastes similar and has the same crunch as it comes hot out of the oven.
I love to make this when my tomatoes are in abundance and the great thing about it, is that its not fussy on the type you have, so mix them all up to make this sweet sauce. I have gifted this for christmas and its really been popular, I've run out again.
