Frozen spinach, on the other hand, has already been blanched and drained, making it a more convenient option for some recipes. However, frozen spinach can still benefit from a quick squeeze or rinse to remove excess water.
Chopping and Slicing
Chopping or slicing spinach can help to release excess water from the cells of the leaves. This is especially useful when working with fresh spinach, as it allows the salt or other methods to penetrate deeper into the leaves.
Storing Spinach
Proper storage can help to reduce the water content of spinach. Store fresh spinach in a breathable container or bag, and keep it refrigerated at a consistent temperature below 40°F (4°C). This will help to slow down the metabolic process and prevent the spinach from becoming soggy or wilted.
Conclusion
Removing excess water from spinach can be a bit of a challenge, but with the right methods and techniques, you can achieve a more flavorful and textured dish. Whether you’re using the salting and squeezing method, a wringer or food mill, centrifugation, or cooking and straining, there’s a way to get the most out of this nutrient-dense leafy green. By following the tips and tricks outlined above, you’ll be well on your way to spinach mastery. So go ahead, give one of these methods a try, and watch your spinach dishes transform into culinary masterpieces!
