The tomatoes are basically the same, just dried differently.
The Sun Dried Tomatoes are dried in the sun, and require the addition of sulfites to the product.
The Fresh Dried are air dried in low heat ovens and have no additives.
Pure Sun Dried™ Tomatoes combine the best of both worlds; partially dehydrated, then finished under the sun. All the flavor with none of the additives — no salt or preservatives.
