Tips
Use a mandoline or sharp knife to slice potatoes paper-thin for best results and even cooking.
Keep clarified butter warm but not hot when brushing to prevent potatoes from cooking prematurely.
Pat fish dry before seasoning to help potato crust adhere better and achieve crispier results.
Good to Know
Best served immediately. Sauce can be made 1 day ahead and gently reheated.
Potato slices can be cut 2-3 hours ahead and kept in cold water. Sauce can be prepared earlier in day.
Serve immediately while potato crust is crispy and fish is hot.
Common Mistakes
Slice potatoes evenly to prevent uneven cooking and ensure proper wrapping.
Don't overheat pan to avoid burning potato crust before fish cooks through.
Pat fish completely dry to prevent steam from making potato crust soggy.

FAQ
Can I make this without truffle paste?
Yes, substitute with mushroom paste, porcini powder, or even sautéed mushrooms for an earthier but more affordable flavor profile.
What if my potato crust falls apart?
Ensure potatoes overlap sufficiently and use enough clarified butter to help bind. Practice the folding technique and work gently but firmly.
How long will the sauce keep?
Truffle sauce keeps refrigerated for 2-3 days. Reheat gently and whisk in fresh butter before serving to restore smooth texture.
