About

I enjoyed this recipe during one of my trips and have been wanting to make it since. At my last grocery expedition, I found those wonderful absolutely gorgeous green tomatoes and I had to get them.  Of course, not having the full recipe thus had to have fun creating with the few ingredients that I was given then.  The replication was pretty yummy.
By using tomatoes you lighten up the heaviness of the regular potato gratin and reducing the amount of heavy cream used. The Parmesan cheese is a bit salty by nature,  thus I decreased the salt used in this dish as well.  One great thing, by coating the potatoes with the cream, this dish can be made ahead of time.  The cream will not allow the potatoes to turn that non-appealing brown due to oxidation.  A normal factor due to starches of the potatoes being exposed to the oxygen.
