Ingredients
Main
- 1360 g potato, peeled and cut into 5cm chunks

Nutrition (per serving)
Method
Fill a large pot with water and add 10g (about 2 tablespoons) of salt. Bring the water to a boil (100°C/212°F) over medium-high heat.
Place the potato chunks into the boiling water and cook until very tender, approximately 12 to 15 minutes.
Drain the potatoes thoroughly and set them aside. Place the empty pot back on the stove.
Melt 30g of butter in the pot over medium heat.
Add the chopped cabbage, most of the scallions (reserve some for garnish), and 5g of salt. Sauté until the vegetables are tender, about 7 minutes.
Pour in the cream and simmer the mixture for 2 minutes.
Return the cooked potatoes to the pot along with another 30g of butter. Mash the mixture until it reaches your preferred consistency.
Continue to cook over medium-low heat, stirring constantly to prevent sticking, until the entire mixture is heated through.
Transfer the mixture to a serving dish and create a well in the center using the back of a spoon.
Place the final 30g of butter into the well. Garnish with the reserved scallion greens and serve immediately.
Chef's Notes
- For the creamiest mash, use starchy potatoes like Russets or Maris Pipers. Ensure they are thoroughly drained after boiling to avoid a watery colcannon.
- Don't overcook the cabbage; it should be tender but still retain a slight bite and vibrant green color. Sautéing it separately before adding to the potatoes prevents it from becoming mushy.
- Warm the cream and butter slightly before adding them to the mashed potatoes. This helps them incorporate smoothly and keeps the dish hot.
- Taste and adjust seasoning with salt and pepper just before serving. The saltiness can change as the ingredients meld.
- The 'well' in the center is traditional for holding melted butter, but don't be afraid to add a dollop of extra butter or even a spoonful of cream on top for richness.
