Sweet Potatoes vs Yams

With the popularity of sweet potato fries you would think sweet potatoes have orange flesh. Wouldn't you?

Being a foodie I thought yams had orange flesh and sweet potatoes had white flesh. I I did a bit of research and learned that’s 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. 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.

Instructions

• Preheat oven to 350°F.
• Peel potatoes and slice thinly. I used a mandoline with 1.5 mm blade.
• In a 4-cup measuring cup add whipping cream, egg, garlic powder, nutmeg and thyme (if using). Stir until combined. Set aside.
• Brush an 8-inch square, glass baking pan (or 2 loaf pans) with oil. Line pan with parchment paper leaving enough excess over 2 sides to cover the pan while cooking.
• Starting with orange potatoes layer them slightly overlapping to cover the bottom of the pan.
• Top each layer with salt and pepper, a generous sprinkling of cheese and some of the cream mixture.
• Repeat alternating orange and white potatoes until you have 6 layers, 3 orange and 3 white.
• Sprinkle top layer with remaining cheese and cream mixture.
• Fold parchment over the potatoes and cover with foil. Can be prepared in advance to this point.
• Bake in preheated oven for 90 minutes, until a knife easily goes through the potatoes.
• Let rest in the pan for 15 minutes. Using parchment, transfer cooked potatoes to cutting board. Cut and serve hot. Garnish with fresh thyme if desired.
