What is the one vegetable that never sold frozen canned or cooked but only fresh?

This is a bit of a trick question! There isn't a vegetable that is *never* sold in any form other than fresh.

Here's why:

* Technology: Freezing, canning, and other preservation methods are constantly improving. What was once difficult to preserve is now possible.

* Demand: As consumer preferences change, there is a growing demand for convenience foods, including frozen and canned vegetables.

However, there are some vegetables that are *rarely* sold frozen, canned, or cooked because:

* Delicate Texture: Some vegetables, like delicate greens (like arugula or spinach) or certain herbs, tend to lose their texture and flavor when processed.

* Flavor Profile: Some vegetables are best enjoyed fresh due to their unique flavor profiles, like heirloom tomatoes or fresh asparagus.

So, there isn't one specific vegetable that's never sold in other forms, but certain vegetables are primarily enjoyed fresh due to their delicate nature or unique flavor.
