Creamy mashed potatoes whipped with tender buttered curly kale, sweet scallions (spring onions), and double cream, baked with a golden crust of aged Irish Cheddar.
Mash boiled potatoes with butter and warm cream until smooth. Fold in cooked shredded kale, sliced scallions, half the cheese, salt, and white pepper.
Transfer colcannon mixture into a buttered baking dish, smoothing the top and swirling with a fork.
Scatter remaining grated Irish Cheddar across the top.
Bake at 200°C for 25 minutes until the cheese is bubbling and has formed a golden-brown crust.
