Blue Dragon Chinese Curry Sauce: Easy Homemade Version

Blue Dragon Chinese Curry Sauce is a ready-made sauce; this recipe is a homemade Chinese-style curry sauce inspired by its mild, savory, gently sweet character, not an exact copy of a proprietary product. It combines curry spices, onion, stock and soy into a smooth sauce for rice, noodles or cooked vegetables, and you can adjust the thickness and warmth to suit your meal.

Ingredients

1 tablespoon neutral oil (15 ml), such as sunflower or vegetable oil
1 medium yellow onion, finely chopped (about 1 cup or 150 g)
2 garlic cloves, minced (about 2 teaspoons or 6 g)
1 tablespoon finely grated fresh ginger (about 6 g)
2 tablespoons mild curry powder (about 12 g)
1 teaspoon ground turmeric (about 3 g)
½ teaspoon ground cumin (about 1 g)
¼ teaspoon ground white pepper (about 0.5 g)
2 tablespoons all-purpose flour (about 16 g)
2½ cups low-sodium chicken or vegetable stock (590 ml)
1 tablespoon soy sauce (15 ml)
2 teaspoons granulated sugar (about 8 g)
1 teaspoon rice vinegar (5 ml)
1 tablespoon cornstarch (about 8 g), mixed with 2 tablespoons cold water (30 ml)
Fine salt, up to ¼ teaspoon (about 1.5 g), only if needed after tasting

Instructions

Prepare the ingredients. Finely chop the onion, which takes about 5 minutes. Mince the garlic and grate the ginger, about 4 minutes, then measure the spices, flour, stock and seasonings, about 4 minutes. Keeping the ingredients ready makes it easier to stir the sauce continuously as it cooks.
Soften the onion. Warm the oil in a medium saucepan over medium heat. Add the onion and cook for 6 minutes, stirring regularly, until soft and translucent. Keep the heat moderate rather than browning the onion; browned edges can give the finished sauce a toastier flavor and darker color.
Add the aromatics. Stir in the garlic and ginger and cook for 1 minute. They should smell fragrant but not turn brown. If the pan looks dry or the garlic starts catching, lower the heat before proceeding.
Toast the spices. Add the curry powder, turmeric, cumin and white pepper. Stir constantly for 1 minute so the spices coat the onion and warm through. A brief toast helps bring out their aroma; prolonged cooking can make them bitter.
Stir in the flour. Sprinkle the flour over the onion and spice mixture. Stir for 1 minute, scraping the bottom and sides of the pan, until no dry flour remains. This short cook helps prevent a raw flour taste and gives the sauce a little body.
Add the stock and simmer. Pour in the stock gradually, whisking as you go to loosen the flour mixture and avoid lumps. Add the soy sauce, sugar and rice vinegar. Bring the sauce to a gentle simmer, then cook for 10 minutes, stirring from time to time. Keep it at a quiet bubble rather than a hard boil.
Blend until smooth. Take the pan off the heat and blend the sauce for about 1 minute with an immersion blender, until the onion is fully incorporated. Keep the blender head submerged to limit splashes. If using a countertop blender, follow its instructions for hot liquids and vent the lid safely; never seal hot sauce in a blender jar.
Adjust the thickness. Return the pan to low heat. Stir the cornstarch and cold water again, then drizzle the slurry into the simmering sauce while whisking. Cook for 2 minutes, until glossy and lightly thickened. Taste before adding salt, since the stock and soy sauce already contribute saltiness. The sauce should coat the back of a spoon; add a splash of stock if you prefer it thinner.

Tips

Choose a mild curry powder. Curry powders vary by brand, and some are much hotter or more pungent than others. Start with a mild blend if you want a sauce close to the gentle, rounded style associated with Chinese takeaway curry. Add extra heat at the table rather than trying to correct an overly spicy pan.
Prevent lumps and scorching. Add the stock in stages while whisking, especially at the start, when the flour mixture is thickest. Once the sauce simmers, stir around the bottom of the saucepan every minute or two. A heavy-based pan and medium-low heat give you more control than high heat.
Make it gluten-free if needed. Replace the all-purpose flour with 1 tablespoon cornstarch (about 8 g) mixed with 2 tablespoons cold water (30 ml), and leave out the separate cornstarch slurry listed for thickening. Add the replacement slurry gradually near the end and simmer for 1 to 2 minutes. The sauce will be a little glossier and less rounded than one thickened with a flour roux. Use gluten-free soy sauce or tamari as well.
Use a jar when convenience matters. Blue Dragon Chinese Curry Sauce is already prepared, so warm it according to the package directions rather than adding the full list of ingredients here. For a quick meal, add cooked vegetables or another cooked topping to the warmed jar sauce. This homemade recipe is useful when you want to control the seasoning or make a batch from pantry ingredients.

Serving Suggestions

Spoon the warm sauce over steamed jasmine or long-grain rice, allowing enough sauce to coat the rice without drowning it. It also works over egg noodles or thin wheat noodles; toss the noodles with a little sauce first, then serve extra at the table. For a simple vegetable plate, serve it with steamed broccoli, carrots, peas, mushrooms or green beans. Cook the vegetables until just tender so they keep some texture and do not dilute the sauce.

To make the sauce part of a more substantial dinner, serve it with separately cooked tofu, prawns or chicken and a side of rice. If cooking chicken specifically for this meal, check the thickest part with a food thermometer and cook it to the USDA FSIS safe minimum internal temperature of 165°F (74°C). Keep the sauce separate until the protein is cooked, then spoon it over the top or simmer the cooked pieces in the sauce just long enough to warm through. A small bowl of sliced scallions or chili oil lets people add a fresh or spicy finish to their own portion.

Variations

Make it warmer. Add ¼ teaspoon cayenne pepper (about 0.5 g) with the other spices, or serve chili oil alongside the finished sauce. Increase the heat in small increments: spice blends differ, and cayenne can take over the gentle curry flavor quickly.

Make it richer. Replace ½ cup (120 ml) of the stock with unsweetened coconut milk. The result will be creamier and slightly sweeter, rather than as close to a classic glossy takeaway-style sauce. Add it with the stock and taste before adding the full amount of sugar.

Add vegetables to the pan. Stir in 1½ cups (about 200 g) of thawed peas, sliced mushrooms or small cooked carrot pieces after blending. Simmer until the vegetables are hot and tender. If using raw vegetables, cook them separately first or allow enough additional simmering time; the stated cooking time applies to the sauce as written.

Use a different thickener. For a lighter sauce without flour, omit the flour and make a slurry with 1½ tablespoons cornstarch (about 12 g) and 3 tablespoons cold water (45 ml). Whisk it into the simmering stock mixture near the end and cook until thickened. Cornstarch gives a shinier, slightly more gel-like finish, so add it gradually and stop when the texture suits your dish.

Storage and Reheating

Cool the sauce promptly and refrigerate it within 2 hours of cooking, in a clean, covered container. It keeps for 3 to 4 days in the refrigerator. If you have made a larger batch, freeze it in meal-sized portions for up to 2 months for best quality. Leave a little room in each freezer-safe container for expansion. Thaw frozen sauce in the refrigerator rather than on the counter.

Reheat only the amount you need in a small saucepan over low to medium-low heat, stirring often. Add a tablespoon or two of water or stock if it has thickened in the refrigerator, and heat until steaming throughout. If the sauce has been combined with leftover meat or another cooked dish, reheat the leftovers to 165°F (74°C), checking with a food thermometer. Avoid repeatedly cooling and reheating the same batch; portioning it before storage makes that easier.

Frequently Asked Questions

Is this an exact Blue Dragon sauce copycat?
No. It is a homemade Chinese-style curry sauce inspired by the mild, savory profile of a prepared Blue Dragon curry sauce. Commercial recipes and seasoning balances are proprietary, and the result can vary depending on your curry powder, stock and soy sauce. The recipe gives you a similar kind of versatile sauce while letting you control its salt, sweetness and thickness.

Can I make the sauce without a blender?
Yes. Chop the onion as finely as you can and whisk the sauce thoroughly as it simmers. It will have a more rustic texture, but it will still taste good. For a smoother result without an immersion blender, press it through a fine-mesh sieve, or use a countertop blender with the manufacturer’s instructions for hot liquids.

Why is my curry sauce too thin?
First, let it simmer gently for another minute or two; it may need time to reduce. If it is still too thin, mix 1 teaspoon cornstarch with 2 teaspoons cold water and whisk that into the simmering sauce. Add more only after the first addition has cooked for a minute, because the sauce thickens as the slurry heats.

Why did the sauce turn out too thick?
Flour, cornstarch and simmering time all affect the final consistency. Whisk in warm stock or water a tablespoon at a time until the sauce pours the way you want. If it becomes too thin after adjusting, simmer it gently for a short time, stirring often, rather than adding more thickener straight into the pan.

Can I make it ahead?
Yes. Make the sauce, cool it promptly and refrigerate it in a covered container for up to 3 to 4 days. It may set more firmly as it chills, so loosen it with a little stock or water while reheating. You can also freeze portions for up to 2 months for best quality, then thaw them in the refrigerator before reheating.

What can I use instead of rice vinegar?
Use an equal amount of mild cider vinegar or white wine vinegar. Both add the small touch of acidity that balances the savory stock and sugar, although the flavor will be slightly different. Avoid strongly flavored vinegars, which can distract from the curry spices.
