It's just potatoes, salt, olive oil, and vinegar.
But the ability to make such a deceptively simple dish with these ingredients isn't falling-off-the-log simple.
There's picking the perfect potatoes.
Then there's cooking them to just the correct point of doneness.
Then there is peeling them while still very hot.
Then there is slicing them thick enough to keep from falling apart.
Then there is working fast so the potatoes will still be warm enough to make magic with the vinegar when it is splashed over the top.
Then of course there is using just the right amount of salt to bring out the flavor.
And finally there is the liberal drizzle of a flavorful olive oil. (Preferably bright green, newly pressed, and unfiltered.)
And, yet again, I made a meal of this one single dish. This chapter could turn me into a vegetarian.
