Description

This impressive looking dish of Scalloped White and Sweet Potatoes is a make-ahead dish perfect for any special occasion like Mother’s Day or a holiday dinner. Take this scalloped potato dish to a potluck dinner and people will be asking for the recipe. They will notice that you went ‘all out’, but your time and effort is invested before the event so you can relax and enjoy.

I don’t think going all out needs to mean long ingredient lists or unusual ingredients. Nor does it need to involve special pans and getting stressed out. To me it means having fun and challenging yourself to be creative. Take a favourite recipe and put some effort into the presentation. This dish shows that you took the time to make something special and that is always appreciated.

Flourless Scalloped Potatoes

Traditional scalloped potato recipes often use flour. To make them gluten free you can simply replace the wheat flour with rice flour, potato flour, a flour blend or even cornstarch. This recipe is a decadent dish made without flour. Seasoned whipping cream and Gruyere cheese are the luscious secret ingredients. Hold the low-fat, non-fat recipes for now, a special occasion calls for all the flavour that comes from full fat dairy products.

Naturally the contrast of the orange and white coloured flesh of the potatoes is what makes the presentation. So when you go grocery shopping that is what you want to come home with. With the popularity of sweet potato fries you would think sweet potatoes have orange flesh. Wouldn’t you?

Sweet Potatoes vs Yams

Being a foodie I always thought yams had orange flesh and sweet potatoes had white flesh. After a bit of research I think this may actually be true. But it’s more complicated than that. Sweet potatoes come in varieties and depending on the variety, the flesh can vary from white to orange and even purple. Yams are a white tuber not commonly available but because of a labelling law some sweet potatoes are labelled as yams. When sweet potatoes came to North America shippers and produce suppliers needed to distinguish them from potatoes. So they just called them yams. That is one of those ideas that sounded good at the time. 

So my advice is just buy something orange and something white and you’ll be happy. If you’re interested in the history you can read Sweet Potatoes 101.
