FAQ

Can I use cold smoked salmon instead?

Yes, but reduce salt as cold smoked salmon is saltier than hot smoked. The texture will be slightly different but equally delicious.

What if I don't have gruyere cheese?

Cheddar, swiss, or fontina work well. Choose a cheese that melts smoothly and has good flavor when heated.

How long will leftovers keep?

Store covered in refrigerator up to 3 days. Reheat in 350F oven until warmed through, about 15-20 minutes.
