The deceptively named lava bread is a Welsh delicacy. (Or it is in the south at least, I cannot speak for those strange people in the north.) It has nothing to do with volcanoes nor does it meet the commonly accepted definition of bread.

Its basic ingredient is in fact a kind of seaweed, the variety known as Palmaria palmata, or dulse, which is collected from the seashore, boiled into a mush, rolled in oatmeal and then fried. It is normally served as an accompaniment to the traditional British breakfast of bacon, eggs, sausages etc, in the same way as black pudding is served in the North of England.

It crops up all over South Wales but is particularly big in Swansea.

To be perfectly honest, lava bread is a vile, disgusting concoction that tastes of nothing more than salt and sand and ought really to be banned under the UN chemical Weapons convention. I have no idea why people persist in eating the stuff and why restaurants in Wales will present otherwise edible food with 'leek and lava bread sauce'. Perhaps the tourists like it.
