- Start by peeling your baby red potatoes and cutting them into cubes. I recommend about 1-inch pieces for even cooking. Once they’re all chopped up, give them a rinse to remove any excess starch. Toss them into a large pot, covering them with water. 
- Make sure to add a generous pinch of salt to the water. This step adds flavor right into the potatoes as they cook. 
- Turn the burner on high and allow the water to come to a rolling boil. Once boiling, reduce the heat slightly and maintain a gentle boil. Let the potatoes cook for about 15-20 minutes or until they’re fork-tender. 
- A quick tip: You can test by poking a cube with a fork. If it slides off easily, they’re ready! 
- Once the potatoes are done cooking, carefully drain them in a colander. This is when you can really start to feel the excitement! 
- Return the drained potatoes back to the pot and set it over low heat for a minute. This helps evaporate any extra moisture, giving you the creamy texture that everyone loves. 
- Add the unsalted butter to the potatoes, followed by the shredded smoked gouda cheese, sour cream, and prepared horseradish. 
- Use a potato masher or a hand mixer to blend everything together until it reaches your desired consistency. Don’t be afraid to let some lumps linger; they add character! 
- Now it’s time to season! Sprinkle in the sea salt and give it a taste. If you want that zing, consider adding a bit more horseradish; it’s all about personal preference. Just remember: a little can go a long way, so adjust according to your taste. 
- To complete this masterpiece, transfer the mashed potatoes to a serving bowl. Top with freshly chopped chives. They not only add color but also enhance the flavor. Now, the world is your oyster! Serve them hot alongside your main dish.
