Understanding Tofu Packages and Measurements
The standard grocery store tofu block is not a uniform product when it comes to volume. While most blocks are sold by weight, typically 14 to 16 ounces (396 to 450 grams), the amount of usable, measured tofu will vary dramatically based on two main factors: the tofu's firmness and how you intend to use it. A block of silken tofu, for instance, contains a high amount of water, which will be incorporated into a purée, resulting in a different volume than a very dense, extra-firm block that has been heavily pressed and cubed.
Tofu Firmness and Its Effect on Volume
Not all tofu is created equal. The density and water content of each variety play a crucial role in determining its final volume when measured by cups. Here is a breakdown of what to expect from common types:
- Silken Tofu: With its custardy texture and high water content, silken tofu is often puréed for sauces, dressings, and desserts. A standard package will yield a specific volume when blended. A 14-ounce package of Mori-Nu Silken Tofu, for example, produces about 1.25 cups of puréed tofu.
- Soft Tofu: Softer than firm tofu, this variety is still solid enough to be handled. When puréed, a 1-pound (450g) block yields around 1.75 cups. If crumbled, the volume might differ slightly due to the incorporation of air.
- Firm Tofu: This is the most versatile type for cooking and a common block size is 1 pound (450g). When cubed, this amount will give you approximately 2.5 cups. Crumbled firm tofu, which traps more air, will measure closer to 2 cups by volume.
- Extra-Firm and Super-Firm Tofu: These varieties have the least water content and are the densest. After pressing, they offer a very solid product. The volume per pound will be the most consistent and dense, with less variation depending on the preparation method. A 14-ounce (396g) block of extra-firm tofu will yield slightly less in volume than a 16-ounce block of firm tofu, and it will be much denser per cup.
How to Accurately Measure Your Tofu
For the most precise results, especially for recipes where volume is important, follow these steps:
- Drain the Tofu: The first and most critical step is to remove the excess liquid. Open the package and drain the water. This prevents your recipe from becoming watery and ensures a more accurate measurement.
- Press Firm Tofu: For firm or extra-firm tofu, pressing is essential. Wrap the block in a clean kitchen towel or paper towels and place something heavy on top, like a cast-iron skillet or a few cookbooks. Let it press for 15-30 minutes to squeeze out more moisture. This will affect its final measured volume but is crucial for a better texture and accurate results in cooking.
- Prepare as per Recipe: Once drained and/or pressed, prepare the tofu according to your recipe's instructions—whether that's cubing, crumbling, or puréeing. This is the moment you measure the tofu in cups.
- Measure and Adjust: Use a standard dry measuring cup for accurate volume. Keep in mind that different textures will pack differently. A cup of densely-packed puréed tofu will be heavier than a cup of loosely-packed, crumbled tofu.
Comparison of Tofu Volumes by Firmness and Preparation
The following table illustrates the typical volume yield from a 1-pound (450g) package of tofu, based on its firmness and preparation method.
| Tofu Type | Preparation Method | Approximate Volume (in cups) |
|---|---|---|
| Firm Tofu | Cubed (1/2" cubes) | 2.5 |
| Firm Tofu | Crumbled | 2 |
| Firm Tofu | Puréed | 1.75 |
| Soft Tofu | Puréed | 1.75 |
| Silken Tofu (Mori-Nu) | Puréed | 1.25 |
Practical Tips for Cooking with Tofu
- Weighing is Best: If precision is paramount, especially for baking, using a digital kitchen scale is the most accurate method. A 1-pound block is approximately 450 grams, and most modern recipes provide metric weights as well.
- Freezing for Texture: Freezing firm or extra-firm tofu and then thawing it dramatically changes its texture, making it chewier and sponge-like, which helps it absorb marinades better. While this doesn't drastically change its overall volume, it affects the finished product's weight and consistency.
- Adjusting for Water: Remember that the total package weight includes the water. When you drain or press the tofu, the final weight and volume of the usable product will be less than the net weight stated on the packaging. The nutrition facts and serving sizes on packages are generally for drained, raw tofu.
- Hand Measurements in a Pinch: If you are without measuring cups, using your hand can be a good approximation for servings, though not for precise volume. A quarter-cup serving of tofu is equivalent to about 2 ounces by weight.
Conclusion: Getting the Right Measurement
So, how many cups are in a package of tofu? The definitive answer depends on the firmness and preparation method. A 1-pound block of firm tofu will typically yield about 2.5 cups when cubed, while a softer variety will result in a different volume, especially when puréed. By draining and pressing your tofu, and using the correct preparation method, you can accurately measure the volume you need for any recipe. For maximum accuracy, especially in baking or detailed meal planning, relying on a kitchen scale in addition to cup measurements is the most reliable approach. Understanding these variables ensures that your tofu dishes turn out perfectly every time.
