All-Purpose Flour (Best Option)
1:1 by weightAll-purpose flour has a protein content typically between 10-12%, which is lower than bread flour but still sufficient to thicken curry sauces effectively. The gluten development is moderate, so the sauce remains smooth without becoming overly dense.
When using all-purpose flour, whisk it thoroughly into the curry liquid to avoid lumps and cook it long enough to eliminate the raw flour taste. Adjust liquid levels slightly if the sauce thickens more or less than expected.
Compared to bread flour, the final curry will have a slightly lighter texture but will retain the desired viscosity and mouthfeel, making it an excellent and accessible substitute.
