Hot smoked salmon and potato gratin FAQ:

What is the baking time for the gratin?

Bake the gratin covered with aluminum foil for 45 minutes at 375°F (190°C), then remove the foil and bake for an additional 20-25 minutes until the top is golden brown and the potatoes are tender.

How do I know when the potatoes are done?

The potatoes are done when they are tender when pierced with a fork. This should be checked after the total baking time of approximately 65-70 minutes.

Can I use a different type of cheese?

Yes, you can substitute cheddar cheese with other cheeses like Gruyère or mozzarella, but this will change the flavor of the dish slightly.

How should I store any leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through.

What can I substitute for heavy whipping cream?

You can use half-and-half or a non-dairy alternative like coconut cream, but note that this may alter the texture and creaminess of the gratin.

Cooking Tips:

- Use a mandoline slicer to get evenly thin potato slices for a more uniform cook.

- Ensure you whisk the heavy cream and milk together well to distribute the flavors evenly.

- Let the gratin rest for a few minutes after baking to allow the sauce to set before serving.

- For a crispy top layer, consider adding breadcrumbs with the cheddar cheese during the last 10 minutes of baking.
