- ✓Lingonberries or a dollop of skyr can be added as a garnish for a touch of Icelandic flair.
🔄 Variations
- Add other root vegetables like carrots or parsnips along with the potatoes.
- Incorporate a splash of white wine into the sautéed vegetables for added depth of flavor.
- For a dairy-free version, use a plant-based milk and cream alternative, and omit the heavy cream.
