What curry roux should I buy?
Any Japanese curry roux blocks work. Common options are S&B Golden Curry, Vermont Curry, or Java Curry. Choose mild for kid-friendly, medium for balanced heat, or hot if you like a little heat.
How much roux should I use?
It depends on the brand and how thick you like it. For 3 1/2 cups broth, start with about 4 oz (a small box, or roughly half of a larger family pack). Simmer 5 to 10 minutes after it melts. If you want it thicker, add more roux a piece at a time (many people land closer to 6 to 7 oz total). If it gets too thick, loosen with a splash of broth or water.
Can I use chicken breast instead of thighs?
Yes. Cut it slightly larger and add it a bit later. Simmer just until it is cooked through, then turn the heat down. Breast dries out fast if you blast it.
Why did my curry turn out thin?
Usually one of three things: too much liquid, not enough roux, or you boiled hard after adding roux. Keep it at a gentle simmer once the roux goes in and give it 5 to 10 minutes to thicken. If it is still thin, add a bit more roux.
Why is my curry grainy or clumpy?
Add the roux off the boil (low heat, no rolling bubbles), then stir until fully dissolved. If it still looks clumpy, keep stirring on low heat and it usually smooths out. Worst case, you can whisk aggressively for 30 seconds like you mean it.
How do I make it taste more like restaurant curry?
Try one small upgrade: a teaspoon of soy sauce, a teaspoon of ketchup, or a square of dark chocolate. Pick one. You are building depth, not starting a science project.
