Rumbledethumps - Celtic Potato, Cabbage & Cheese Gratin

“A wonderful combination of mashed potatoes, Savoy cabbage, cheese & chives - baked OR grilled to give a crispy cheesy topping. This is one of my very favourite family recipes - my Mum used to make it, as did her Mum before her! This is a Scottish recipe, similar to Irish Colcannon, which is also a potato & cabbage dish. You can serve this as a vegetable accompaniment or as a light luncheon dish with crusty bread & extra vegetables. P.S. My daughter calls this baked Bubble and Squeak & always asks for it when she comes home from university!”
