Cook Time 40 minutes
Servings 8


  • 3 Tbsp Butter or Ghee
  • 4 Tbsp All-Purpose Flour
  • 2 Tbsp Japanese Curry Powder


  1. Melt the butter in a heavy-bottom pan on the stove over medium heat. Sprinkle the flour over the butter.

Recipe Notes

• Two tablespoons of curry powder creates a moderately spicy roux. Add up to 1 tablespoon more for a spicier flavor.

• Use the roux immediately or store it in an airtight container in the refrigerator for up to one week.

• Substitute half the Japanese curry powder for an equal amount garam masala for a pleasing variation.

• Add 1 tablespoon per cup of stock/water when making Japanese curry.
