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.

Swirls and layers of flavor, perfect for a small Swirl Plate!

Leek Stock: 100 Days of Recipes, Day 59

It feels like it's the pinnacle of harvest time at the Tailgate Markets, with flowers and plant starts everywhere, strawberries and blueberries abounding, piles of greens, radishes, squash, carrots, garlic... it goes on and on (and don't forget the cheeses, eggs, fish, poultry, and meats), and the tomatoes are JUST starting! It's a huge blessing of abundance, and I feel like it anchors my week when I get to stroll an early Saturday morning away through the crowds and chat with the wonderful people who produce all this goodness.

I've also been more mindful of getting as much as I can out of all the wonderful locally produced foods I bring home, and that's included looking at the parts that often get relegated to the stock pot or even the trash bin. I love making good veggie stocks out of skins, tops, and other bits and pieces, and I usually keep a bag or two in the freezer on hand to collect all those scraps. It didn't occur to me to make specific stocks out of just one ingredient (possibly because I have a skinny 'side' freezer, and I have to be creative about the 'stock' items I keep in addition to all my other freezer residents). That was about to change.

My Tailgate finds for the weekend - those lovely, wide, bands
of green are my leek tops!

This weekend, I picked up a generous bunch of beautiful leeks, and unlike those I might get at the grocery store, these have not had their green tops trimmed down, so there was a LOT of extra greens. To be honest, to save time I might just lop off the top third (the really green parts) and toss them, saving the rest of the stalk (minus the bulb) for stock. But they smelled so good, and were just so beautiful, I couldn't believe they wouldn't be good to eat with the proper treatment - I knew they could be a great steaming bed or wrapper for fish, and I had seen them used to tie up a 'bouquet garni', but I hoped for more. A quick scan online showed me multiple recipes using leek greens, so I knew I wanted to keep them for something better than 'just stock'.

Leeks pre-blanche: I wish you could smell this - leek heaven!

They are a lot tougher, and are more fibrous, than the softer parts near the bulb, so I cut them into smaller pieces and then blanched them. Actually, I'd say I did more of a double or triple blanching - not just a quick toss in boiling water, but more of a simmer for about 5 minutes. I was multi-tasking so ended up letting the leeks cool in the liquid on the stove before draining them into a big bowl.

I changed my mind - NOW I wish you could smell this!

So now I have these beautifully softened leek tops, ready for a nice leek tart, or maybe inclusion in a meatloaf, or a curry, or who knows what else? Even better, I have this GORGEOUS leek stock. I really didn't even think about that part when I was simmering away, but just before I was about to drain the liquid into the sink, I got a whiff and realized I needed every drop of this goodness as well. My freezer has an ice maker, so I don't have ice cube trays. I used my popsicle molds so I could get some stock into the freezer for later use. These other two jars will soon become a base for a soup (cauliflower/sweet potato is what I'm thinking right now), and also a braising liquid for other cooking this week.

I had ideas for several uses of the blanched leek tops - they got a LOT smaller,
so maybe one really nice tart for the tops, and several uses ahead for the stock!

This recipe is more for an ingredient to be used in another recipe. In short: I cut up the leek tops, put them in a stock pot, covered them with water, and brought them to a boil. I lowered the heat to a simmer and let them go for about 5-7 minutes. They cooled in the pan, and then I drained the leeks, squeezing out the excess liquid, which I retained in jars and molds for the freezer. The leeks were then double bagged, labeled and also headed to the freezer.

I'm sure you'll see them pop up again in another recipe!
