Can Curry Powder Be Substituted For Curry Paste. If you have black mustard seeds or cumin seeds, try toasting them in skillet before adding them to your new spice blend. Combine cumin, coriander, chilli, turmeric and pepper in a small bowl (or large plastic bag if making a big batch).
If you want a typical indian type curry flavor, use powder. Thai red curry paste is another excellent substitute for yellow curry paste. The powder is definately different than the paste.
