It is good though, if you're having a party You can make - though not cook - it in advance, to help with the labor intensity of it all.
It comes from Ina Garten - and it's a gratin. And I made it as the Thanksgiving potatoes, though 710 made mashed, as he didn't want to mess with tradition.
Everything came out fine, but I won't say it met my expectations. I think my expectations were just different than Ina intended.
Baking Potatoes - 4 medium
Shallots - 8-9
Cream - 2 Cups
Butter - 6 T
Sugar - a pinch
Canola Oil - 1 Cup
Sage leaves - 10
Salt and Pepper
With a mandolin, slide peeled potatoes at the 1/8" width. Soak in cold water to remove some starch and then drain and pat them dry.
Put a layer of potatoes on bottom of a baking dish. Drizzle with cream and season with salt and pepper.
Repeat this layering until potatoes are gone. Pour rest of cream over the potatoes evenly.
Cover and bake for 30 minutes; remove the cover and continue baking until the cream has been absorbed, the potatoes are cooked through and the top is browned, 30 to 45 minutes longer.
Slice shallots 1/4" thick.
Heat butter, add shallots to a medium heated pan, add sugar. Slowly cook, stirring occasionally, until golden brown and caramelized, about 40 minutes; season with salt and pepper.
Here you're also supposed to deep fry sage leaves in the canola oil for less than a minute to get them crisp. I know my family well enough that this isn't for them, so I didn't actually do this part.
But if you did - evenly distribute the shallots and sage leaves on top of the potatoes.
Since we made this dish at home, we waited to put shallots on until we got to my mother's house. Then we popped it back into a 350 oven for 15 minutes to warm up.
Looked good. Tasted good. Though honestly, I hoped the shallots would have crisped up a bit. Wishful thinking since they were caramelized, but that's where my unrealistic expectations were dashed.
I would totally do this again, maybe with a modification. Maybe instead of frying the sage, do it with the shallots, not caramelize them. But that might just be me.
