Freezing is ideal for preserving vegetables that have a high water content like peas, corn, and broccoli.

Dehydration is suitable for preserving herbs, mushrooms, and root vegetables like potatoes and beets.

Fermenting is ideal for preserving vegetables like cabbage, cucumbers, and carrots, which can be pickled and fermented to create sauerkraut, kimchi, and other fermented foods.
