(Part 1) The Sweet Potato – A Culinary Hero

The moment I smell a baked sweet potato, I'm transported back to cozy Japanese evenings, where the warmth of the oven blends perfectly with the scent of this humble root vegetable. In Japan, sweet potatoes are more than just a side dish, they're a versatile ingredient that shines in both savory and sweet dishes. They bring a unique combination of sweetness, a satisfyingly soft texture, and a touch of earthiness that's just irresistible.

A Sweet Potato by Any Other Name...

You might think all sweet potatoes are the same, but in Japan, there's a world of difference. First, we have the satsumaimo (薩摩芋), the most common type you'll find in supermarkets. It has a beautiful orange flesh and a distinct sweetness that's perfect for both savory and sweet dishes. Then there's the Beniharuka (紅はるか), a real treat with its deep purple skin and pale yellow flesh. It's known for its higher sugar content and a richer, more concentrated flavour that's often used in desserts.

And then there's the Murasakiimo (紫芋), the showstopper with its vibrant purple flesh. This one has a slightly milder sweetness than its orange counterparts and is frequently used to add a touch of vibrant colour to desserts, snacks, and even rice dishes.

More Than Just Sweet

You might think sweet potato is just a side dish, but the Japanese know how to use it in all sorts of creative ways. It's not just about the sweetness; the sweet potato adds a depth of flavour that complements both savory and sweet dishes. You'll find it in warming stews, rich soups, stir-fries, and even as a key ingredient in some of Japan's most popular desserts.

They're perfect for adding a touch of sweetness to a savory dish, like a sukiyaki (a sizzling hot pot dish with thinly sliced beef, tofu, and vegetables), or a oden (a comforting winter stew with daikon radish, boiled eggs, fish cakes, and more). They can also be used to create a smooth, creamy texture in a soup or a stew. And don't even get me started on the desserts! Imagine daigakuimo (sweet potatoes candied in a sweet glaze), imo-mochi (sweet potato mochi), or even a simple baked sweet potato drizzled with honey. The possibilities are truly endless.
