Standard 15-Ounce Cans: The Most Common Conversion
When a recipe calls for two cans of beans, it usually refers to the standard 15-ounce size. This can size is simple. A single 15-ounce can, once drained, contains roughly 1.5 cups of cooked beans. This volume is consistent across many bean types. Therefore, combining the contents of two standard 15-ounce cans will give a total of approximately 3 cups of beans. This measurement is crucial for dishes from stews to homemade dips and chilis.
Factors Influencing Bean Volume
While the 1.5 cups per 15-ounce can is a reliable rule of thumb, some variables can slightly affect the final volume. The amount of liquid added, the bean type, and the draining process can play minor roles. However, these variations are usually negligible for most home cooking. The most critical step is always to drain and rinse the beans thoroughly before measuring to ensure accuracy. This process standardizes the volume and helps reduce the sodium content, often high in canned products.
Comparison of Canned vs. Dried Beans
For many cooks, the choice between canned and dried beans is a balance of convenience. Below is a detailed comparison.
| Feature | Canned Beans | Dried Beans |
|---|---|---|
| Convenience | Excellent; ready to use after draining. | Low; requires soaking and cooking. |
| Cost | More expensive per serving. | Economical, especially in bulk. |
| Volume Yield | Consistent volume per can (e.g., 1.5 cups from a 15 oz can). | Expands significantly during cooking (1 cup dry yields about 3 cups cooked). |
| Sodium Control | Often high in sodium, though rinsing helps. | Sodium-free; you control the salt. |
| Flavor & Texture | Can have a bland flavor; texture is soft. | Superior flavor and a firmer texture. |
| Storage | Long shelf life. | Lasts for years when stored properly. |
Scaling Up to Larger Can Sizes
Many brands offer larger 28-ounce cans. The conversion for these is straightforward. A 28-ounce can yields about 3.5 cups when drained. This means two large 28-ounce cans will provide approximately 7 cups of beans. Always check the label for specific weight, but the 3.5-cup rule is a reliable guide for drained beans.
Using Aquafaba: The Canning Liquid
Although draining the beans is standard practice, the liquid from the can, known as aquafaba, is popular for its uses. It has emulsifying and binding properties, making it a vegan substitute for egg whites. For example, it can be whipped into peaks to create meringues. Keep the aquafaba separate from the beans. The liquid will affect volume and consistency if mixed in.
A Quick Guide to Bean Volume Measurement
Here's a breakdown of how to measure your beans:
- Step 1: Open the Cans. Use a can opener to safely open both cans of beans.
- Step 2: Drain and Rinse. Pour the contents into a colander. Rinse under cool water until the water runs clear. This removes excess sodium.
- Step 3: Measure the Volume. Use a measuring cup to portion out the beans. For two 15-ounce cans, you will get about three cups total.
- Step 4: Use in Your Recipe. Add the measured beans to your dish.
These steps ensure consistent recipes. For precision, a kitchen scale is even more accurate, though volume measurement is adequate.
Conclusion: Simplifying Your Recipes
Two standard 15-ounce cans of drained beans equal approximately 3 cups. Two 28-ounce cans will yield about 7 cups. This knowledge streamlines recipe preparation and ensures consistent results. A little bit of knowledge about can conversions goes a long way. For more detailed information on bean conversions and recipe ideas, refer to reputable food resources like Serious Eats. Understanding this measurement is essential for any cook using canned goods, balancing convenience with accuracy.
