Tips

Tip 1

Score duck skin in crosshatch pattern before marinating to help fat render and achieve crispy skin. Use a sharp knife to cut through skin only, not into meat.

Tip 2

Let duck rest after searing to redistribute juices. The final oven heating brings it to perfect medium-rare temperature while keeping the skin crispy.

Tip 3

Make pickled garnishes while duck marinates overnight. The longer marination time for all components develops deeper flavors throughout the dish.

Good to Know

Storage

Cooked duck keeps in refrigerator for 2 days. Store pickled garnishes separately for up to 1 week. Sweet potatoes best served fresh but can be reheated.

Make Ahead

Marinate duck up to 3 days ahead. Pickle garnishes up to 2 days ahead. Sweet potatoes can be parcooked earlier in day and finished before serving.

Serve With

Serve immediately while duck is warm and skin is crispy. Present on warmed plates to maintain temperature of all components.

Common Mistakes

Watch

Don't flip duck too early to avoid rubbery skin.

Watch

Don't skip resting period or juices will run out when sliced.

Watch

Don't overcook sweet potatoes in oven or they'll fall apart during glazing.

FAQ

Can I substitute regular duck for Moulard duck breasts?

Yes, regular duck breasts work fine though they may be smaller. Adjust cooking time accordingly and check for doneness with meat thermometer targeting 125-130F for medium-rare.

What if I can't find sake kasu for the marinade?

White miso makes an excellent substitute and is more widely available. It provides similar umami depth and tenderizing properties. Use the same amount as called for.

How long will the pickled garnishes keep in the refrigerator?

Both pickled shallots and apples will keep for up to one week refrigerated in sealed containers. The flavors actually improve after the first day of marinating.
