Directions:
1. Boil the potatoes and kohlrabi separately (use two pots if needed) until tender, 20 to 35 minutes depending on size. Drain, reserving ½ cup of the liquid from either vegetable.
2. Peel the potatoes and kohlrabi. Mash them together in a large bowl. (Larger, more mature kohlrabi should be run through a food mill to remove fibers.)
3. Melt the butter in a small pot over medium heat. Add ¼ cup of the milk or cream. Heat until almost simmering and remove from heat.
4. Pour the butter mixture over the potato mixture. Add ½ teaspoon salt and pepper to taste and beat until fully combined and smooth. Add another ¼ cup of milk or cream for more rich creaminess, if desired. If you want a smoother texture, slowly stir in the reserved cooking water until it reaches the desired consistency. Season with more salt and pepper to taste. |
