You should read my last 2 posts to find out how I suddenly got really into these Kettle Cooked Lay's. They are pretty addictive. They're all crunchy and potato-y and yummy. Anyways, here's a quickie. The Vinegar on these is bomb, a little bit less abrasive compared to the regularly cooked Salt and Vinegar chips, but still pretty strong stuff. It doesn't burn your lips but you are still getting a good kick on the tongue. The chips have that stiff Kettle Cooked crunch to them and a nice potato flavor.
I would say if you were looking at both on the shelf and debating which one to buy; these are the ones you get when you want a more potato flavored, thicker cut, crunchy experience with a zing... and the regular Lay's would be for when you want a lighter, airy chip with a ton of Vinegar on it. They are both good, just depends on your preference. As for the Sea Salt, it just makes you want them more (its a marketing thing), flavor wise, salt is salt. You aren't getting big chunks of salt so it doesn't really make a difference. The only difference comes in the fact that they are fried in small batches which help it retain potato taste. I think I would crave these somedays and the regular Salt and Vinegar Lay's on other days. Either way, it's a bomb flavor. MMM.
