Izakaya Sakura Kuro Curry: A Culinary Journey to Japan

I remember the first time I tasted Kuro Curry. It was in a tiny, dimly lit Izakaya tucked away on a side street in Tokyo. The aroma alone, a complex blend of spices, sweetness, and savory depth, was intoxicating. The rich, almost black sauce clung beautifully to the perfectly crisp tonkatsu, and with each bite, I was transported. It wasn’t just a meal; it was an experience, a taste of authentic Japanese comfort food that I’ve been trying to recreate ever since.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 2 hours 9 minutes
• Total Time: 2 hours 39 minutes
• Servings: 4-6
• Dietary Type: Not specified (can be modified for gluten-free or vegetarian)

Ingredients

Curry

• 1 tablespoon oil
• 1 lb pork butt, cut into 1/2 inch cubes
• Salt & freshly ground black pepper, as needed
• 4 medium onions, sliced thin
• 1 1⁄2 cups red wine
• 2 1⁄2 cups water or vegetable stock
• 2 carrots, cut 1/2 inch cubes
• 2 large yukon gold potatoes, cut into 1/2 inch cubes
• 2 teaspoons kosher salt (use less if you use regular salt)
• 1 tablespoon Tonkatsu sauce or 1 tablespoon Heinz 57 steak sauce
• 1 tablespoon tomato paste
• 1⁄4 cup applesauce
• 1 teaspoon black garlic oil (Mayu)
• 1⁄2 cup peas
• 2 ounces bittersweet chocolate (good quality)

Roux

• 3 tablespoons butter
• 1⁄3 cup flour
• 2 tablespoons curry powder (S&B Japanese Curry Powder recommended) or 2 tablespoons garam masala
• 2 teaspoons fresh ground black pepper (more or less depending on how spicy you want it)

Equipment Needed

• Large saute pan
• Bowl
• Lid for saute pan
• Whisk
• Pot or Dutch oven

Instructions

1. Heat the oil in a large saute pan over medium-high heat. The pan should be large enough to hold the pork cubes in a single layer.
2. Season the pork cubes with salt and freshly ground black pepper to taste. Add the seasoned pork to the hot pan in a single layer. Avoid overcrowding the pan, as this will steam the meat instead of browning it. If necessary, brown the pork in batches.
3. Let the meat brown on one side undisturbed, then use tongs or chopsticks to flip them over and brown the other side. The goal is to develop a rich, flavorful crust on the pork.
4. Once the pork is nicely browned, transfer it to a bowl and set aside. Reduce the heat to medium-low.
5. Add the sliced onions to the pan. Cover the pan with a lid and cook for 10 minutes. This helps soften the onions and release their moisture.
6. Remove the lid and continue caramelizing the onions until they are dark brown and glossy (about 1 hour). Stir occasionally to prevent sticking and ensure even browning. Be patient; this step is crucial for developing the deep, complex flavor of the curry. The onions should be very soft and sweet.
7. Add the browned pork, red wine, water (or vegetable stock), carrots, potatoes, salt, Tonkatsu sauce (or Heinz 57 steak sauce), tomato paste, and applesauce, and black garlic oil to the pan with the caramelized onions. Bring the mixture to a boil over high heat.
8. Once boiling, reduce the heat to medium-low and simmer partially covered until the carrots are tender (about 45 minutes). The liquid should be simmering gently, not boiling vigorously.
9. While the curry simmers, prepare the roux. In a separate saucepan, melt the butter over medium-low heat.
10. Add the flour to the melted butter, stirring constantly with a whisk. Continue cooking and stirring until the mixture turns a golden brown color (this takes about 5-7 minutes). Be careful not to burn the roux, as this will impart a bitter flavor.
11. Add the curry powder (or garam masala) and black pepper to the roux and stir to incorporate. The mixture will turn into a paste. Remove from the heat and set aside until the carrots in the curry are tender.
12. Make a batch of tonkatsu (breaded pork cutlets) or grill some vegetables to serve the curry sauce on. If you’re making tonkatsu, start this process about 30 minutes before the curry is finished simmering.
13. Finish the curry by ladling some of the hot liquid from the pot containing the meat and vegetables into the roux. Whisk vigorously until there are no lumps. This tempering process prevents the roux from clumping when added to the rest of the curry.
14. Pour the tempered roux mixture back into the pot with the rest of the curry and gently stir until the curry is thickened. The curry should thicken noticeably as it simmers.
15. Taste the curry for salt and adjust as needed. The flavor should be rich, balanced, and slightly sweet.
16. When you’re happy with the flavor, add the peas and chocolate to the curry and stir until the chocolate is melted and incorporated. The chocolate adds a subtle depth and richness to the curry.
17. Slice the tonkatsu (if using) or portion the grilled vegetables and plate along with some cooked rice.
18. Pour the Kuro Curry sauce generously over the plated food and serve immediately.

Expert Tips & Tricks

• Caramelizing onions: This step is key to the rich flavor. Don’t rush it! A low and slow caramelization brings out the natural sugars in the onions.
• Browning the pork: Sear the pork properly. A good sear develops deep flavors that are essential for the final dish.
• Adjusting the spice: Taste the curry as it simmers and adjust the amount of black pepper or curry powder to your preference.
• Roux Consistency: Make sure your roux is smooth. This will guarantee a smooth and lump free kuro curry.
• Make Ahead: The curry can be made a day or two in advance and reheated. The flavors actually meld and deepen over time!

Serving & Storage Suggestions

Serve Izakaya Sakura Kuro Curry hot over rice, tonkatsu, or grilled vegetables. Garnish with pickled ginger or scallions for added flavor and visual appeal.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze the curry in individual portions for up to 2 months. To reheat, thaw the curry in the refrigerator overnight and gently warm it in a saucepan over medium heat, stirring occasionally. You may need to add a splash of water or stock to thin the curry slightly if it has thickened too much.

Variations & Substitutions

• Vegetarian: Omit the pork butt and use vegetable stock instead of water. Add extra vegetables such as mushrooms, eggplant, or bell peppers for added flavor and texture.
• Gluten-Free: Use a gluten-free flour blend for the roux and ensure that your Tonkatsu sauce or Heinz 57 steak sauce is gluten-free. Many Japanese curry powder brands are gluten-free, but always check the label.
• Spicier Curry: Add a pinch of cayenne pepper or a chopped chili pepper to the curry while it simmers for a spicier kick.
• Sweeter Curry: Add a tablespoon of honey or maple syrup to the curry for a sweeter flavor.

FAQs (Frequently Asked Questions)

Q: What gives this curry its distinctive dark color?
A: The deep, dark color comes from the long caramelization of the onions and the addition of bittersweet chocolate.

Q: Can I use a different type of meat instead of pork butt?
A: Yes, you can substitute beef chuck or even chicken thighs for the pork butt. Just adjust the cooking time accordingly.

Q: What is black garlic oil (Mayu)?
A: Black garlic oil is garlic that has been slowly cooked until it ferments and turns black. It has a unique, umami-rich flavor and adds depth to the curry. If you cannot find it, you can omit it or substitute a small amount of regular garlic oil.

Q: Can I freeze this curry?
A: Absolutely! This curry freezes very well. Store in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating.

Q: Is S&B Japanese Curry Powder necessary, or can I use any curry powder?
A: While S&B Japanese Curry Powder is recommended for its authentic flavor profile, you can use other curry powder blends, such as garam masala, if you prefer. Just keep in mind that the flavor will be slightly different.
