Japanese curry powder (カレー粉) is a blend of spices, herbs, and aromatics that is used to season a variety of Japanese dishes such as curry rice (カレーライス), curry udon(カレーうどん), and curry bread(カレーパン). This recipe comes from one of Japan's largest spice companies.
Mix the spices in a bowl to evenly distribute everything.
Heat a frying pan over medium-low heat and add the vegetable oil and spices. Toast the spices while constantly stirring until the oil is evenly distributed and the spices are very fragrant (about 2-3 minutes).
1 tablespoon vegetable oil
Transfer the Japanese curry powder out of the pan to let it cool to room temperature. Store the curry powder in a non-reactive airtight container until you're ready to use it.
