Chervil’s delicate anise flavor pairs with butter and fleur de sel to add richness to spring’s first baby potatoes.
What to buy: Chervil is available at gourmet grocery stores and farmers’ markets. If you can’t find it, substitute a mixture of Italian parsley and tarragon.
Fleur de sel is a hand-harvested sea salt that is moister than other salts and has a nice crunch and a distinct mineral taste—all qualities that stand out in this dish. It can be found at gourmet grocery stores.
