Substitution Guide

✅ Best Substitute

Homemade Roux with Curry Powder

It gives brighter spice and less sweetness. It takes about 10 extra minutes.

⚠️ Acceptable

Curry Sauce Flakes or Paste

They melt faster and work the same way. The flavor is a little lighter.

🚫 NEVER Use

Thai Curry Paste

It has no flour, so the sauce stays thin. Chili and lemongrass also change the dish.
