How to press tofu

What pressing actually does

Tofu is sold sitting in water. That water is there to stop the block from drying out and cracking on the shelf, and it soaks into the tofu itself over the weeks it spends in a refrigerated case. A standard sixteen ounce block of extra-firm tofu will typically give up somewhere between two and four tablespoons of liquid under moderate pressure, and softer blocks give up considerably more.

That liquid is the problem. Put an unpressed block in a hot pan and the water at the surface has to boil off before the surface can rise above the boiling point of water. Until it does, nothing browns. You are steaming, not frying, and the pan temperature drops while you wait. By the time the surface finally dries out, the inside has overcooked into something rubbery.

Pressing removes enough of that water that the surface dries within seconds of hitting the pan. Everything else about tofu cooking gets easier once that is true. Crust forms faster, less oil is absorbed, marinade has somewhere to go, and the pieces hold together when you turn them.

Method one: a plate, a towel and something heavy

This is the default and it costs nothing. It removes roughly as much water as a dedicated press and takes about the same amount of time.

1. Open the package, pour off the water, and lift the block out.
2. Wrap it in a clean kitchen towel, or three or four layers of paper towel.
3. Set the wrapped block on a plate or a rimmed baking sheet, so the runoff has somewhere to go.
4. Put a second plate on top, then something heavy on that. A cast iron skillet is ideal. Two or three cans, a heavy pot, or a stack of books on a tray all work.
5. Leave it for twenty to thirty minutes. Swap the towel halfway if it is soaked through.
6. Unwrap and pat the surface dry before cutting.

Do not go straight to maximum weight on a soft or medium block. Too much pressure too fast splits the tofu rather than draining it. Start with something modest and add more after ten minutes if the block is holding its shape.

Method two: a dedicated press

A press applies even pressure across the whole face of the block, contains the runoff, and does not need a towel. In practice the finished tofu is not dramatically better than the towel method, but the process is tidier and more repeatable, and you can put the whole thing in the refrigerator and forget about it.

The designs fall into three groups. Screw presses use threaded posts and apply the most force, which suits people who want very dry tofu and are willing to tighten the knobs every few minutes. Spring presses apply steady moderate pressure with no attention at all. Self-contained container presses hold everything in one box that doubles as a marinating and storage vessel.

Any of the three works. The design differences matter less than whether you will actually use the thing, which mostly comes down to how annoying it is to clean.

Method three: the fifteen-minute version

When you forgot to plan ahead, heat helps. Wrap the drained block in paper towel, put it on a plate, and microwave it for two minutes. The block will release a surprising amount of water as it heats. Pour that off, replace the towel, and press under weight for another five to ten minutes while you prepare everything else.

The tofu comes out slightly cooked at the edges, which is harmless, and slightly firmer overall, which is useful. This is not quite as effective as thirty minutes under a skillet, but it gets you most of the way there in a quarter of the time.

A second shortcut: cut the block into slabs first, then press. More surface area means faster drainage. Slabs half an inch thick will press in about ten minutes under moderate weight, and you can cut them into cubes afterward.

Method four: freeze and thaw

Freezing a block and thawing it does something pressing cannot. Ice crystals push the protein structure apart, and the thawed block releases water freely when squeezed by hand, no weight required. It also comes out chewier and far better at absorbing marinade.

This is the best option if you have a day of notice, and it removes more water than any press. The full method, including how the texture changes and when to avoid it, is on the freezing guide.

How long, by tofu type

Super-firm tofu sold in a vacuum pack rather than a water bath has already been pressed at the factory. Buying it is a legitimate way to skip this page entirely, and the tofu types guide explains what you give up in exchange.

How to tell when it is done

The block should feel noticeably denser and slightly springy rather than yielding. Press a corner with your thumb: it should resist and not weep. The surface should look matte rather than wet, and a piece of paper towel laid on it should come away barely damp.

Height is the other tell. A well-pressed block loses roughly a fifth of its thickness. If it looks the same as when it went in, either the weight was too light or the towel was already saturated and had nowhere left to absorb.

What to do next

Once the block is pressed, cut it into three quarter inch cubes or half inch slabs, toss with a spoonful of cornstarch and a good pinch of salt, and cook it hot. The crisping guide covers the pan, the oil and the timing, and basic crispy tofu is the whole thing written as a recipe.
