It's generally best to press and slice tofu *before* refrigerating it for stir-fry, as this allows for better moisture removal and more efficient marinating.
Preparing tofu for stir-fry involves pressing it to remove excess water, which allows it to absorb flavors better and achieve a crispier texture when cooked. Slicing the tofu before refrigerating after pressing offers several advantages:
Improved Moisture Removal: Slicing increases the surface area, allowing more water to be pressed out. This is crucial for achieving a crispy stir-fry.
Enhanced Marination: Pre-sliced tofu absorbs marinades more evenly and efficiently. The marinade penetrates deeper into the tofu, resulting in a more flavorful dish.
Convenience: Having the tofu pre-sliced saves time when you're ready to cook. It's already prepped and ready to go into the stir-fry.
After pressing and slicing, store the tofu in an airtight container in the refrigerator. It's best to use it within a few days for optimal freshness and texture.
For extra crispy tofu, consider freezing it after pressing and slicing. Freezing changes the texture, creating small ice crystals that, when thawed and pressed again, result in a more porous tofu that soaks up even more marinade and crisps up beautifully in the stir-fry.
