Japanese curry sauce mixes are sold in blocks or powdered form. All you need to do after sauteeing the vegetables and protein is to add the mix to the pot, and it’s done! Additionally, you can make the mix at home. It won’t have the preservatives and additives that the commercial versions tend to have, meaning it has a shorter expiration date. But the perk is that you can customize the flavor, spice level, and thickness to your preference. Wish to learn more about Japanese cooking?
