Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.
-
Melt the butter in a heavy pan over a low heat and stir in the flour.
-
Cook 20 minutes, stirring often, until the roux is the colour of peanut butter and smells nutty.
-
Stir in the curry powder, garam masala and turmeric and cook 2 minutes.
-
Take off the heat and stir in the tomato purée, honey and soy sauce. Set the roux aside.
-
While the roux cooks, heat the oil in a second pan and fry the onion for 8 minutes, until golden.
-
Add the carrot and potato and cook 2 minutes.
-
Pour in the stock, add the grated apple and salt, and simmer 15 minutes until the potato is tender.
-
Ladle a little hot stock into the roux and whisk smooth, then stir the loosened roux back into the pan.
-
Simmer 5 minutes, stirring, until thick and glossy.
-
Taste, correct the salt, and serve over rice.

Tips for Success
- Twenty minutes for the roux. Peanut-butter colour is the target.
- Loosen the roux with hot stock before it goes into the pan.
- The grated apple is standard and it is what rounds the edges.
Why the Method Is What It Is
The roux is cooked for twenty minutes over a low heat, which is far longer than a French one, and the colour goes from pale to the shade of peanut butter. That browning is where Japanese curry gets its particular round, almost sweet depth. Take it further and it turns bitter; stop early and the sauce tastes of raw flour, which is the fault of nearly every homemade version.
