Making colcannon with kale is a straightforward process that allows you to create this incredible dish with ease. Follow these steps:

1. Prepare the Potatoes: Peel and chop the russet potatoes into even-sized pieces. Place them in a large pot, and cover with cold water. Add salt and bring to a boil over medium-high heat.
2. Cook the Potatoes: Once boiling, reduce the heat to medium and simmer for about 15-20 minutes or until the potatoes are tender when pierced with a fork. Drain the potatoes well.
3. Cook the Kale: While the potatoes are cooking, bring a separate pot of water to a boil. Add the chopped kale and blanch for 3-4 minutes until vibrant green. Drain and rinse under cold water to stop cooking. Set aside.
4. Mash the Potatoes: In the same pot the potatoes were boiled in, add the drained potatoes, whole milk, and unsalted butter. Mash them until smooth and creamy.
5. Combine Ingredients: Stir in the blanched kale, salt, and black pepper. Mix until well combined. Taste and adjust seasoning if needed.
6. Add Green Onions: For extra flavor, fold in the chopped green onions and chives (if using) into the mashed mixture.
7. Serve Warm: Transfer the colcannon to a serving bowl and create a small well at the top. If desired, add a small pat of butter in the center for extra richness.

These steps will help you craft a delicious colcannon dish that your family and friends will love.
