Welsh Rarebit is a traditional 18th Century dish British dish and is a favourite here in the UK. It is actually a glorified, enticing and visual classy cheese on toast. It can be either served as light main dish or hearty snack. This Traditional Vegan Welsh Rarebit I made a few years back but I have altered the recipe to make it gluten free. Here I use tapioca flour. I love the strong intense flavours of this Traditional Welsh Rarebit.
