Soaking tofu in salt water for 15 minutes will result in a better crust and texture. Set the block of tofu in a bath of warm salty water and allow it to soak for 10-15 minutes before pressing out the excess water. Soaking in salt water pulls out excess moisture and tightens the proteins on its surface. This step is completely optional but you might want to try it out in some of your favorite tofu recipes.
