Best Holiday Entertaining Tip
I love the idea of choosing a tried-and-true recipe for a special occasion. This means you know the recipe is a hit and you can put some effort into the presentation.
This recipe is written with the nice presentation in mind but go ahead and make it now, just like any scalloped potato dish. They you'll know how fabulous it is and when you need a side dish for the next special occasion you'll have this one in mind.

Best Tools for Making Scalloped Potatoes
If you’ve ever wanted to buy a mandoline, this is the reason to buy it. You can make uniformly thin slices of any vegetable with a few different tools but the mandoline is made for this job.
Sweet Potatoes vs Yams
The contrast of the orange and white coloured flesh of the potatoes is what makes this dish special. (And the whipping cream in my opinion). When you go to the store that's what you need to buy.
With the popularity of sweet potato fries you would think sweet potatoes have orange flesh. Wouldn't you?
Being a foodie I always thought yams had orange flesh and sweet potatoes had white flesh. I don't keep information like that in my head so I did a bit of research. It turns out that’s actually true but it’s more complicated than that.
Sweet potatoes come in varieties (of course they do!) and the colour varies depending on the variety. The flesh can range from white to orange and even purple.
Yams are a white tuber not commonly available. According to my research because of a labelling law some sweet potatoes are labelled as yams. Apparently when sweet potatoes came to North America shippers and produce suppliers needed to distinguish them from potatoes. They simply called them yams and the rest is history.
