Welsh Onion Cake

Welsh comfort food at its finest, this traditional onion cake - known in Wales as teisien winwns or teisen nionod - is made with layers of thinly sliced potatoes and soft onions topped with bits of butter or drenched in melted butter, seasoned and baked until sticky and golden. Onion cake is generally consumed throughout the whole of Wales and enjoyed either on its own or as an accompaniment to various meat dishes. For a richer version of Welsh onion cake, cheese is often added, and many recipes call for the crumbly, white kind such as Caerphilly cheese.
