Roasted Purple Yam Stew: A Culinary Adventure in Color and Flavor

My first encounter with purple yams was purely accidental. I was wandering through a bustling Asian market, searching for inspiration for a new soup, when these vibrantly hued tubers caught my eye. Their deep, regal color was unlike anything I’d ever seen in the produce aisle. Intrigued, I bought a few, not quite sure what I would do with them, but completely captivated by their unique beauty. That whim turned into this deeply satisfying roasted purple yam stew, a dish that’s as comforting as it is visually stunning.

Ingredients

• 4 ears corn
• 1 lb shrimp, peeled and deveined, retaining shells
• 4 cups water
• 1 carrot, chopped
• 1 teaspoon thyme
• 2 small onions, chopped, divided
• 2 lbs yams, purple
• 4 tablespoons olive oil
• 1 tablespoon Chinese five spice powder
• 1 tablespoon kosher salt
• 6 chili peppers, Calabrian, diced
• 1 tablespoon fresh galangal root, grated
• 1 ounce ginger, grated
• 2 tablespoons garlic, grated
• 5 ounces shiitake mushrooms, sliced (stems removed)
• 2 ounces green onions, sliced

Equipment Needed

• Large pot
• Baking sheets
• Blender
• Strainer or cheesecloth

Instructions

1. Begin by preparing the corn. Bring enough water to cover the corn to a boil in a large pot. Add a pinch of salt, and boil for 8 minutes. Extract the corn, but retain 4 cups of the water. Cut the corn from the cobs and set aside, retaining the cobs for the stock.

2. Next, craft the flavorful stock. Combine the corn cobs, shrimp shells, 4 cups of corn water, carrot, thyme, and one chopped onion in a large pot. Bring the mixture to a boil, then reduce the heat and lower to a simmer for 4 hours. This long simmer will extract every bit of flavor from the shells and vegetables. Strain the contents of the pot to retain the stock, discarding the solids. This step can be done a day ahead.

3. While the stock simmers, preheat your oven to 350 degrees F (175 degrees C). Now, prepare the purple yams. Peel the yams until the vibrant purple inside is exposed. Cut them into 1-inch chunks, discarding any parts that aren’t purple to ensure a consistent color in the finished stew.

4. In a bowl, toss the cubed yams with 2 tablespoons of olive oil, kosher salt, and Chinese five spice powder. The five spice powder adds a lovely warmth that complements the sweetness of the yams.

5. Arrange the seasoned yams on baking sheets, making sure they aren’t touching to allow for even roasting. Cook for 20 minutes, or until they are softened somewhat. Remove from the oven and set aside.

6. While the yams are roasting, heat the remaining 2 tablespoons of olive oil in a large pot over medium heat. Add the remaining chopped onion and sauté until softened, about 10 minutes.

7. Add the diced Calabrian chili peppers, grated galangal, grated garlic, and grated ginger to the pot. Sauté for about a minute, stirring constantly to prevent the spices from burning. The fragrance should be incredible at this point!

8. Add the shrimp to the pan, stirring occasionally to keep the spices from burning. Cook the shrimp on both sides for just a few minutes, until they turn pink and opaque. Remove the shrimp from the pan, leaving the ginger and other contents in the pot, and set the shrimp aside. You don’t want to overcook the shrimp at this stage.

9. Add the roasted yams to the pot, and stir to coat them with the flavorful mixture in the pan. Pour in the prepared stock. Stir, scraping up any browned bits that stick to the bottom of the pan – these add depth of flavor to the stew.

10. Bring the mixture to a simmer, then reduce the heat and cook for another 30 minutes, or until the yams are very soft.

11. Carefully pour the contents of the pot into a blender and puree until smooth. Be cautious when blending hot liquids, and use a spatula to scrape down the sides as needed, since the mixture will be quite thick.

12. Remove the stems from the shiitake mushrooms and slice them into 1/4-inch pieces. Add the sliced mushrooms to the pot and cook for 5 minutes, or until they are tender.

13. Finally, add the cooked corn, cooked shrimp, and sliced green onions to the pot and stir thoroughly to combine.

14. Serve hot.

Expert Tips & Tricks

• Roasting the yams is key: Don’t skip the roasting step! Roasting brings out the natural sweetness of the yams and adds a subtle caramelized flavor that you won’t get from simply boiling them.
• Spice it up (or down): Adjust the amount of Calabrian chili peppers to your liking. If you prefer a milder stew, use fewer peppers or remove the seeds before dicing. For a spicier kick, add a pinch of cayenne pepper.
• Make it ahead: The stock and roasted yams can both be prepared a day in advance to save time. Store them separately in the refrigerator and combine them when you’re ready to finish the stew.
• Blending safety: When blending hot liquids, be sure to vent your blender properly and start on a low speed to prevent splattering.

Serving & Storage Suggestions

Serve the Roasted Purple Yam Stew hot, garnished with extra sliced green onions and a swirl of cream (dairy or non-dairy, depending on your preference). It pairs beautifully with crusty bread for dipping.

Leftover stew can be stored in an airtight container in the refrigerator for up to 3 days. It can also be frozen for longer storage, up to 2 months. Thaw in the refrigerator overnight before reheating.

To reheat, gently warm the stew on the stovetop over medium heat, stirring occasionally, until heated through. You may need to add a little extra broth or water to thin it out if it has thickened during storage.

Variations & Substitutions

• Vegan Version: Omit the shrimp entirely. You can replace the shrimp stock with vegetable broth or a mushroom-based broth for added depth of flavor. Consider adding firm tofu or tempeh for protein.
• Spice Blend Alternatives: If you don’t have Chinese five spice powder, you can create your own blend using cinnamon, cloves, star anise, fennel seeds, and Sichuan peppercorns.
• Yam Variations: While purple yams are the star of this dish, you could experiment with other types of yams or sweet potatoes. Just be aware that the color and flavor will be slightly different.
• Mushroom Medley: Use a mix of different types of mushrooms for a more complex flavor. Oyster mushrooms, cremini mushrooms, or even dried porcini mushrooms would be great additions.
• Coconut Milk: Swirl in some coconut milk at the end for a richer, creamier stew with a hint of coconut flavor.
