Can you make a gnocchi with a starch other than potato? Sweet potato (orange gnocchi!) and Incan purple potato (lavender gnocchi!) I’ve tried in the past, often mixed with sauteed garlic for taste, but I wondered if it would be possible to make gnocchi with another starchy plant, the apple. The look and consistency of potatoes and apples are similar, albeit apples are less dense–they float in water while potatoes sink. This fact ended up nearly being the downfall of the recipe: with traditional gnocchi, you can tell when each gnoccho is done because it floats with the top; with apple gnocchi, this is not a sure indicator. Still, you can still make a successful apple-based gnocchi if you time things well.
This was originally cooked for Oberlin’s Iron Chef Co-op competition in 2009, in which the Iron Chef ingredient was, appropriately, apples; and our co-op’s menu won first place!
Ingredients (serves about 4 — scale for your crowd)
For the gnocchi:
- 3 apples, peeled, cored and diced (pie apples work best)
- 7 medium potatoes, diced (Yukon golds preferred)
- unbleached white flour
- 2 cups cloudy apple cider
- an egg beater, potato masher, whisk, or industrial-strength dough mixer.
- cinnamon
ALLERGY NOTE: Gnocchi is traditionally made with flour, a very unfriendly substance to those with Celiac or other wheat allergies. However, it should be noted that this is the ONLY glutenous ingredient! Though I have not tried it, I have read of others preparing gnocchi with arrowhead or brown rice flour. I would suggest, based on my own experience, adding a pinch of xantham gum if you go this route; and, if you are not vegan, an egg as well. This will help give the gnocchi its consistency. Don’t forgo this most delicious and springy of pastas just because you’re wheat-free! Please let me know if you’ve tried this.
For the sauce:
- 2 cups cloudy apple cider
- butter or olive oil (or both)
- light cream, whole milk or cream substitute (soy milk works fine)
- garlic, minced
- 1 apple, grated with cheese grater–heavier, fall apples work better
- 1 apple, diced
- flour
- cinnamon
Gnocchi instructions:
Bring 1 medium and 1 large pots of water to a rolling boil. Boil the potatoes (large pot) and the apples (small pot) until they are soft; it actually doesn’t matter how small the pieces are, though the smaller they are the faster this will cook. Add one cup of apple cider to the boiling apple water.
When they are soft, drain both pots and put the potatoes and apples in a mixing bowl. Mash them with a potato masher or other implement until they are well-mashed with no lumps, and the apple mass is indistinguishable from the potatoes. As you are doing this, bring another pot of water to rolling boil, adding a dash of salt to the water.
When the mixture of potato and apple is steaming and no longer wet, add 1/2 cup of cider and a tablespoon of cinnamon and keep mixing. Start adding flour to the mixture, several handfuls at a time, mashing the mixture to keep it homogeneous. Eventually, when the ratio of flour to apple/potato is about 1:1, the dough should be a sticky, smooth mixture, much like a bread dough. Rip off a small piece of dough and throw it in the water; if it doesn’t sink, add more flour and mix again.
Some people are very meticulous about the way their gnocchi looks, going so far as to use special gnocchi shaping tools. You can do this if you wish, but personally I don’t mind having odd shapes for my gnocchi, though I do try to keep them a regular size–balls of about a 1cm diameter. To make your gnocchi balls, first you have to make snakes: covering your hands with flour, remove balls of dough and roll them into snakes on a cutting board, with a diameter of 1cm or so. Be liberal with the flour. Cut the snakes into pieces of about 1cm width.
Now, here is the tricky part with the timing. Traditional gnocchi sinks in the boiling water and rises when it is cooked. You want your apple-gnocchi dough to sink at first and then rise–but rather than remove immediately, keep it in for about 60 additional seconds after it rises, then remove the gnoccho ball with a strainer. Set them on a plate to steam and dry.
Sauce Instructions:
You can cook gnocchi with all kinds of different traditional Italian sauces, but for apple gnocchi you’re pretty much required to make an apple reduction sauce. Sautee the minced garlic in liberal amounts of olive oil or butter (or both) on medium-low heat. Before the garlic browns, add the diced apple. As they cook a bit and soak up the oil, add the shredded apple pieces. After those cook for a minute, add about half a cup of apple cider. Depending on how sweet the cider is, you’ll want to adjust how much you use–if it’s very sweet, you’ll want to use less. At this point you should also add your milk or cream, though this is optional–however, it will change the consistency of the sauce and make it more creamy (obviously). If you use soy milk, opt for a thick, unsweetened and plain variety. Let the apple cider and cream reduce in the pan on low heat. To increase thickness, add a few pinches of flour. When the sauce is appropriately thick add a dash of salt and sprinkle with cinnamon.
This was served with a host of other apple-themed dishes including apple-gorgonzola pizza, apple-cinnamon ice cream and a lovely apple-walnut salad. I was only in charge of the apple gnocchi, however, though all the other dishes were equally delicious.
