Sweet Potato & Leek Top Tortilla Española - 100 Days of Recipes: Day 62

If you come to Asheville (and you really should, you know!), you will find unending possibilities for good food and drink. One of my favorites, and they were even before they were a client, is Cúrate Tapas Bar, and their Tortilla Española is something I love! I also love sweet potatoes, and in fact I like them much more than white potatoes, so as soon as I had this goodness at the restaurant, I began wondering how it would taste with sweet potatoes. 

I kept wondering, and then a wonderful thing happened: chef Katie Button released her Cúrate cookbook, and included was her recipe for the Tortilla. I loved it so much the first time I made it myself, I think I made it easily five more times within as many weeks. I think it's my favorite way to eat white potatoes.

But the question remained, I wonder if I could make a version with sweets? The opportunity presented itself this week when I decided to put together some small bites to celebrate a neighbor's birthday. I was thinking of making the tortilla from the cookbook for the event, adding the blanched leek tops (see Day 59, June 26) from the freezer. Well the day did not go as planned, and I didn't get a chance to shop for the cookbook tortilla, but when I got home, I realized I had the eggs, I had some onions, I had the leek tops, and I had a good pile of sweet potatoes. Here was my chance to test out a new version!

Flipped out of the cast iron pan and onto a platter - perfect for entertaining, because
you can plate it, then get ready and it'll be at a perfect serving temperature
by the time your guests arrive!

I don't always test new recipes when I'm entertaining ... oh wait, yes I do. In fact, I think I make a point to do that, so this fit right in. In addition to the leek tops, I had some beautiful oyster mushrooms from the tailgate that just seemed to want to go in the tortilla, so in they went.

I was a bit rushed from the 'day that did not go as planned', so I didn't think to take any pictures until the plating, but I think the key to making sweet potatoes work for this is to slice them thin, and then watch them in the fry pan and turn them just as they begin to get color. The texture stays really nice in the tortilla!

The recipe below is what I made, following the original recipe out of the Cúrate Cookbook, but adapting for the ingredients I had - the result is sweeter than the original, to be sure, but if you love sweet potatoes, you'll love it. And I may add some more fresh herbs next time to offset the sweetness .. or not - this was really, really good!!

Sweet Potato, Leek Top, and Oyster Mushroom Tortilla

6 eggs, whisked well
1/3 cup blended oil (I used a little olive oil with a little veg oil)
2 large sweet potatoes, peeled and thinly sliced (a bit less than 1/8")
1/2 large yellow onion, 1/16" slices
1 cup blanched leek tops
1 cup sliced oyster mushrooms (loose pack)

Whisk the eggs in a bowl large enough to hold all the ingredients, then set aside near the stove.

Heat the oil in a 10" cast iron or other heavy-bottom pan. Stove tops vary, but you're looking for a medium heat that's a little hotter than medium. Cook the sliced sweet potatoes in batches, turning them often so they don't burn too fast. Adjust your heat as needed. Once you have a nice, light browning on both sides, use a slotted spatula and remove them, shaking off excess oil, to the bowl of eggs, and add a nice pinch of salt. Repeat until you've done all the sweet potatoes. If you still have a lot of oil, pour off the excess and leave just enough to saute the onions. Lower the heat a bit, add the onions to the pan along with the leek tops. Stir to coat with the oil, cover and let them soften for about 3 minutes. Add in the mushrooms and a nice sprinkle of salt, stir to mix, cover and let cook another 3 minutes.

Add the onion mixture to the eggs, stir to combine thoroughly. Add 2 TBSP oil to the pan, and set the heat to medium/low. Pour in the eggs, and spread it out in an even layer. Cook until the underside is golden and the center is set - about 10 minutes.

Place a plate 'face down' on top of the pan, and using towels or oven mitts, flip the tortilla from the pan to the plate. Immediately slide the tortilla back into the pan so you can get a nice browning on the other side. That'll take another 5-6 minutes. 

Loosen the sides of the tortilla with a spatula, then you can either flip it back onto your serving platter, or get a spatula under it and lift it out of the pan and onto the platter.

*Don't cook it until it's solidly firm all the way through, or you may end up with an over-done tortilla. Let it have a little give in the center, and you'll have a nice moisture (think 'over easy' eggs in creaminess, but not as runny) inside.

This is best at room temp, so you can do it up to an hour before serving.
