Blanch the ears in boiling water for 4 minutes, immediately plunge them into an ice bath to stop the cooking, and pat them dry. Cut the kernels off the cob or leave them whole, then seal in airtight bags and freeze.

Wash, core, and score an "X" on the bottom of each tomato. Blanch in boiling water for 1 minute, then plunge into cold water to easily slip off the skins. Place whole or chopped tomatoes on a baking sheet to freeze solid, then transfer to airtight freezer bags.

The Flash-Freeze Method: This is the best technique to prevent the cubes from turning into a giant, solid block. Space the cubes out on the baking sheet so they do not touch each other.

To freeze green beans, wash, trim, and cut them. Blanch the beans in boiling water for exactly 3 minutes, then shock in an ice bath for 3 minutes to halt cooking. Dry completely, spread on a baking sheet to freeze individually, and transfer to airtight freezer bags.

(Shredded): Shred fresh zucchini with a box grater or food processor. Place the shredded zucchini in a clean tea towel or cheesecloth and squeeze out as much moisture as you can. Measure it into 1- or 2-cup portions, place in freezer-safe bags. (Sliced or Chunks): Cut off the ends and chop the zucchini into consistent slices. To prevent the pieces from clumping into one solid block, freeze the slices in a single layer for up to 2 hours before bagging.

Remove wilted outer leaves, chop or shred the cabbage, and blanch it in boiling water for 1.5 minutes. Plunge in an ice bath to stop cooking, drain, dry completely, and freeze in airtight bags.

Flash-freeze the pieces in a single layer on a parchment-lined baking sheet for 1 hour, then transfer to freezer bags. Squeeze out all excess air to prevent freezer burn.

To freeze winter squash (like butternut, acorn, or pumpkin), the best method is to cook and mash the flesh. Simply cut the squash in half, scoop out the seeds, roast until tender, and scoop out the pulp. Cool, mash, and store in freezer-safe bags or containers, leaving about a ½-inch of headspace.

Never freeze raw eggplant, as its high water content turns it into a mushy, bitter mess. Instead, cook it first by roasting, baking, or blanching. To prevent the flesh from turning brown due to oxidation, toss slices in lemon juice or soak them before cooking.
