1 pounds fiddleheads (ostrich fern) – rinsed and trimmed
1 tbsp olive oil
2 tbsp unsalted butter
1 small shallot – finely chopped
2 cloves garlic – thinly sliced
1 medium lemon – zested and juiced
0.5 tsp kosher salt
0.25 tsp black pepper – freshly ground
flat-leaf parsley – chopped (for serving)
Instructions
Clean the fiddleheads by rubbing off any brown papery chaff, trimming 0.25 inch from the stem ends, and rinsing in several changes of cold water until the water runs clear.
Bring a large pot of water to a rolling boil. Add the fiddleheads and boil 8–10 minutes, until bright green and just tender with no raw crunch. Drain and plunge into ice water to stop the cooking, then drain well and pat dry.
Heat the olive oil and unsalted butter in a large skillet over medium heat until the butter foams.
Add the shallot and cook, stirring, until translucent, 1–2 minutes. Stir in the garlic and cook until fragrant, 30–60 seconds.
