## What is Hawaiian Oxtail Soup?

Hawaiian oxtail soup, or *supu ‘ūwī pipi* as it might be referred to conversationally (though the English name is far more common), is a local favorite, often found in restaurants and home kitchens throughout the Hawaiian Islands. Its roots are a blend of Chinese and Hawaiian culinary traditions, reflecting the diverse cultural influences that have shaped Hawaiian cuisine. The soup’s distinctive flavor profile comes from the combination of oxtail, which imparts a rich, gelatinous broth, and Asian spices and aromatics that add depth and complexity. Unlike Western-style oxtail soups that may rely on vegetables like carrots and celery, Hawaiian oxtail soup focuses on showcasing the oxtail’s flavor, enhanced by ingredients like ginger, star anise, dried shiitake mushrooms, and sometimes peanuts or cilantro. It is traditionally served with rice, and often garnished with fresh ginger and green onions. Some variations also include a sprinkle of toasted sesame seeds or a drizzle of sesame oil. The hallmark of a good Hawaiian oxtail soup is incredibly tender oxtail that falls off the bone and a deeply flavorful, slightly sweet broth. The long simmering time is essential for achieving this level of tenderness and extracting the maximum flavor from the oxtail.

## Why This Recipe Works

This recipe is designed to replicate the authentic taste of Hawaiian oxtail soup, focusing on these key elements:

* **Quality Oxtail:** Using high-quality oxtail is crucial. Look for oxtail pieces that are meaty and have a good amount of marbling.
* **Long Simmering Time:** The extended simmering time is non-negotiable. It allows the oxtail to become incredibly tender and releases its rich flavor into the broth.
* **Aromatic Infusion:** The combination of ginger, star anise, and dried shiitake mushrooms creates a complex and fragrant broth that is characteristic of Hawaiian oxtail soup.
* **Balancing Flavors:** The addition of sugar and salt (or soy sauce) helps to balance the flavors and create a harmonious soup.
* **Serving with Rice:** Serving the soup with rice is essential for absorbing the flavorful broth and completing the meal.

## Ingredients You’ll Need

Here’s a breakdown of the ingredients you’ll need to make authentic Hawaiian oxtail soup:

* **Oxtail:** 3-4 pounds, cut into 1-2 inch pieces. The star of the show! Choose meaty pieces with good marbling.
* **Water:** Approximately 12-16 cups, or enough to cover the oxtail in the pot.
* **Ginger:** A 4-inch piece, peeled and sliced. Adds warmth, spice, and aromatic depth.
* **Star Anise:** 4-5 whole star anise. Imparts a licorice-like flavor and complex aroma.
* **Dried Shiitake Mushrooms:** 6-8 mushrooms, rehydrated. Provides umami and earthy notes. Reserve the soaking liquid.
* **Salt:** To taste. Enhances the overall flavor.
* **Sugar:** 1-2 tablespoons. Balances the savory flavors and adds a subtle sweetness.
* **Soy Sauce:** 2-3 tablespoons (optional). Adds umami and saltiness.
* **Green Onions:** For garnish, thinly sliced. Adds a fresh, oniony flavor and visual appeal.
* **Fresh Ginger:** For garnish, thinly sliced. Intensifies the ginger flavor.
* **Cooked Rice:** For serving. Essential for absorbing the flavorful broth.
* **Optional Garnishes:** Toasted sesame seeds, sesame oil, chopped cilantro, roasted peanuts, hot peppers.

## Equipment Needed

* **Large Stockpot or Dutch Oven:** A heavy-bottomed pot is ideal for even heat distribution.
* **Slotted Spoon or Ladle:** For skimming off impurities.
* **Fine-Mesh Strainer:** For straining the broth (optional, for a clearer broth).
* **Cutting Board and Knife:** For preparing the ingredients.
* **Bowls and Spoons:** For serving.

## Step-by-Step Instructions

Follow these detailed instructions to create a truly authentic Hawaiian oxtail soup:

**Step 1: Prepare the Oxtail**

* Rinse the oxtail pieces under cold water. This helps to remove any bone fragments or impurities.
* Pat the oxtail dry with paper towels.

**Step 2: Brown the Oxtail (Optional but Recommended)**

* In the large stockpot or Dutch oven, heat a tablespoon of oil (vegetable or canola oil works well) over medium-high heat.
* Working in batches, brown the oxtail pieces on all sides. This step adds depth of flavor to the soup. Don’t overcrowd the pot, as this will lower the temperature and prevent proper browning.
* Remove the browned oxtail from the pot and set aside.

**Step 3: Build the Broth**

* Add the sliced ginger and star anise to the pot. If the pot has a lot of browned bits from the oxtail, you can deglaze it with a little water or chicken broth, scraping up the browned bits from the bottom of the pot. This adds even more flavor to the broth.
* Cook for a few minutes, until the ginger is fragrant.
* Add the browned oxtail back to the pot.
* Add the rehydrated shiitake mushrooms (reserve the soaking liquid).

**Step 4: Simmer the Soup**

* Pour in enough water to completely cover the oxtail. The water level should be about 1-2 inches above the oxtail.
* Bring the soup to a boil, then immediately reduce the heat to a very low simmer. It should be barely bubbling.
* Skim off any scum or impurities that rise to the surface. This will help to create a clearer broth.
* Cover the pot and simmer for at least 3-4 hours, or until the oxtail is incredibly tender and falls off the bone easily. The longer it simmers, the more flavorful the soup will be. You can even simmer it for up to 6 hours.
* Check the water level periodically and add more water if necessary to keep the oxtail submerged.

**Step 5: Season the Soup**

* After the oxtail has simmered for the desired time, remove it from the pot and set aside to cool slightly.
* Strain the broth through a fine-mesh strainer (optional, for a clearer broth). Discard the solids (ginger, star anise, mushroom stems).
* Return the strained broth to the pot.
* Taste the broth and season with salt, sugar, and soy sauce (if using). Start with the recommended amounts and adjust to your taste. The soup should be savory with a hint of sweetness.
* Shred the oxtail meat from the bones and return it to the soup. Discard the bones and any excess fat.
* Add the rehydrated shiitake mushroom caps back to the soup (slice them if desired).
* Heat the soup through.

**Step 6: Serve and Garnish**

* Ladle the soup over cooked rice in individual bowls.
* Garnish with fresh green onions and thinly sliced ginger.
* Optional garnishes: toasted sesame seeds, sesame oil, chopped cilantro, roasted peanuts, a drizzle of chili oil or a pinch of red pepper flakes for some heat.

## Tips for the Best Hawaiian Oxtail Soup

* **Don’t Rush the Simmering Time:** The key to tender oxtail and a flavorful broth is a long, slow simmer. Resist the urge to shorten the cooking time.
* **Use High-Quality Oxtail:** Look for oxtail pieces that are meaty and have a good amount of marbling. This will result in a richer and more flavorful soup.
* **Skim the Impurities:** Skimming off the scum that rises to the surface during simmering is essential for a clear and flavorful broth.
* **Adjust the Seasoning to Your Taste:** Don’t be afraid to experiment with the seasoning. Add more salt, sugar, or soy sauce until the soup reaches your desired flavor profile.
* **Make it Ahead:** Hawaiian oxtail soup tastes even better the next day. The flavors meld together and deepen overnight. You can make the soup a day or two in advance and store it in the refrigerator. Reheat it gently before serving.
* **Add Other Vegetables:** While traditional Hawaiian oxtail soup doesn’t include many vegetables, you can add other vegetables to the soup if you like. Consider adding daikon radish, carrots, or watercress during the last hour of simmering. However, adding these will slightly alter the ‘traditional’ profile.
* **Use a Pressure Cooker or Instant Pot (with adjustments):** To significantly reduce cooking time, an Instant Pot or pressure cooker can be employed. Brown the oxtail using the sauté function. Then, add all ingredients into the pot, cover with water, and cook on high pressure for 45-60 minutes, followed by a natural pressure release of 15-20 minutes. Then, proceed with the rest of the steps (seasoning, shredding, etc.) as outlined in the original recipe. Note that cooking times may need slight adjustments depending on your specific appliance.

## Variations and Additions

* **Peanuts:** Some recipes call for adding roasted peanuts to the soup. This adds a nutty flavor and crunchy texture. Add the peanuts during the last 30 minutes of simmering.
* **Cilantro:** A sprinkle of fresh cilantro can add a bright, herbaceous flavor to the soup.
* **Hot Peppers:** If you like spicy food, add a pinch of red pepper flakes or a few slices of fresh chili pepper to the soup.
* **Chinese Herbs:** Some variations include other Chinese herbs like dried goji berries or red dates.
* **Rice Noodles:** Substitute the rice with rice noodles for a different texture.

## Serving Suggestions

* Serve hot over cooked rice.
* Garnish with fresh green onions and ginger.
* Offer a variety of garnishes for your guests to choose from, such as toasted sesame seeds, sesame oil, chopped cilantro, and roasted peanuts.
* Serve with a side of soy sauce or chili oil for dipping.
* Accompany the soup with a side of steamed vegetables or a simple salad.

## Storage Instructions

* **Refrigerate:** Store leftover Hawaiian oxtail soup in an airtight container in the refrigerator for up to 3-4 days.
* **Freeze:** Freeze the soup in freezer-safe containers for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

## Frequently Asked Questions (FAQs)

**Q: Can I use a different cut of beef?**

While oxtail is the traditional cut of beef used in this soup, you can substitute it with other cuts, such as beef shanks or short ribs. However, the flavor and texture will be slightly different. Oxtail has a unique richness and gelatinous texture that is hard to replicate.

**Q: Can I make this soup in a slow cooker?**

Yes, you can make Hawaiian oxtail soup in a slow cooker. Brown the oxtail first, then add all the ingredients to the slow cooker. Cook on low for 8-10 hours, or until the oxtail is very tender. Proceed with the rest of the steps as outlined in the recipe.

**Q: How do I rehydrate dried shiitake mushrooms?**

To rehydrate dried shiitake mushrooms, place them in a bowl and cover with hot water. Let them soak for at least 30 minutes, or until they are soft and pliable. Reserve the soaking liquid, as it contains valuable umami flavor that can be added to the soup. Be sure to squeeze out any excess water from the mushrooms before adding them to the soup.

**Q: Can I omit the sugar?**

While you can omit the sugar, it does play an important role in balancing the flavors of the soup. It adds a subtle sweetness that complements the savory and umami notes. If you omit the sugar, the soup may taste slightly less complex.

**Q: What if I can’t find star anise?**

Star anise is a key ingredient in Hawaiian oxtail soup, but if you can’t find it, you can try substituting it with a pinch of anise seed or a small piece of licorice root. However, the flavor will not be exactly the same.

**Q: How do I prevent the oxtail from becoming tough?**

The key to preventing the oxtail from becoming tough is to simmer it slowly and gently for a long period of time. Avoid boiling the soup, as this can cause the oxtail to become tough and dry.
