What is blanching, and why is it important for freezing green beans?
Blanching is a process of briefly submerging green beans in boiling water or steam to inactivate the enzymes that cause spoilage and loss of color, texture, and flavor. This step is crucial for freezing green beans as it helps preserve their quality and nutritional value. By blanching, you can prevent the growth of bacteria and other microorganisms that can cause the beans to become mushy or develop off-flavors.
Blanching also helps to break down the cell walls of the green beans, making them easier to freeze and reheat. This process can be done using either boiling water or steam, with the latter being a more gentle and nutrient-preserving method. The blanching time will vary depending on the method and the desired level of doneness, but it’s essential to follow a tested recipe or guideline to ensure the best results.
How do I blanch green beans before freezing?
To blanch green beans, start by filling a large pot with enough water to cover the beans. Bring the water to a rolling boil, then carefully add the green beans.
