2 c. fresh basil leaves, lightly packed
2 lbs. large Yukon Gold potatoes (approx. 5-6)
1 c. half-and-half
3/4 c. freshly grated Parmesan cheese, plus extra for serving
2 tsp. kosher salt
1 tsp. freshly ground pepper
Bring a large pot of salted water to a rolling boil and fill a bowl with ice water. Add the basil leaves to the boiling water and cook for exactly 15 seconds. Remove the basil with a slotted spoon and immediately plunge the leaves into the ice water to set the bright green color. Drain and set aside. I don't often use the blanching process but it worked best using a large pot for boiling (I used the same pot and water that I used for the potatoes) and a mesh strainer to retrieve the basil leaves in one scoop.
Peel the potatoes and cut them in quarters. Add the potatoes to the same pot of boiling water and return to a boil. Cook the potatoes for 20-25 minutes, until very tender. Drain well, return to the saucepan, and steam over low heat until any remaining water evaporates.
I continue to believe one of the best purchases I made this summer was this block of imported Parmesan from Jimmy's. A great value for the number of times a recipe has called for freshly grated Parmesan.
In a small saucepan over medium heat, heat the half-and-half and Parmesan cheese until the cream simmers.
Place the basil in a food processor fitted with the steel blade and puree. Add the hot cream mixture and process until smooth.
With a handheld mixer with the beater attachment, beat the hot potatoes in the pot until they are broken up. Slowly add the hot basil cream, the salt and pepper and beat until smooth. If the potatoes need to be reheated, cover and cook gently over low heat for a few minutes. Pour into a serving bowl, sprinkle with extra Parmesan cheese, season to taste, and serve hot.
I added a little bit more half-and-half just before serving to make a bit more creamy - B was excited!!
What I would do next time:
Remember to prepare my bowl of ice water before dropping the basil into the hot water. 15 seconds is not much time to prepare the ice bath.
I went a little heavy on the pepper and would do a better job of taste-testing prior to serving.
