Tofu should be pressed to remove excess water before refrigeration to improve its texture and prevent it from becoming waterlogged. This also helps it absorb marinades better.
Tofu is packaged in water, and while this keeps it fresh, it also means it contains a lot of moisture. If you refrigerate tofu without pressing it first, it will continue to release water, resulting in a softer, less desirable texture. Pressing tofu removes this excess water, making it firmer and allowing it to brown more effectively when cooked. Here's how to do it:
Remove the tofu from its packaging and drain the water.
Wrap the tofu block in several layers of paper towels or a clean kitchen towel.
Place a heavy object on top of the wrapped tofu, such as a cast-iron skillet or a stack of books. You can also use a dedicated tofu press.
Let the tofu press for at least 30 minutes, or up to a few hours, changing the paper towels as needed if they become saturated.
Once pressed, the tofu can be stored in an airtight container in the refrigerator for several days. It's best to cover it with fresh water, changing the water daily, to maintain its freshness.
For even firmer tofu, consider freezing it after pressing. Freezing and thawing tofu changes its texture, making it chewier and more absorbent. After thawing, press it again to remove even more water.
