Everything You Need to Know About Taro

Every week we get Down & Dirty, in which we break down our favorite unique seasonal fruits, vegetables, and more.

Today: Get to know a tropical tuber you might have been missing out on.

If you thought Jerusalem artichokes were confusingly named, it turns out tropical tubers might be even more perplexing. In Roots, Diane Morgan explains that “taro” is the common name for four different root crops: 1) malanga or American taro (Xanthosoma sagittifolium); 2) giant swamp taro (Cyrtosperma chamissonis); 3) false taro or giant taro (Alocasia macrorrhiza); and 4) true taro (Colocasia esculenta). 

True taro is what we are talking about today, but even once we’ve established that, the nomenclature can still be bewildering. Taro goes by a number of different names (satoimo, elephant’s ear, cocoyam, etc.), which is not all that surprising considering that, like all things, taro has its own name in every different place that it’s grown and that taro is grown in more than 40 countries. It's actually one of the world’s oldest cultivated plants, as Morgan elaborates: “References suggest that it has been domesticated for over five thousand years in tropical Southeast Asia, cultivated even before rice or millet.”

Taro is sometimes referred to as "taro root," too, but while we're getting technical, the part of the plant we eat that is grown underground (the leaves and leaf-stems are edible, too) is not the roots, but rather the corms and cormels.

There are more than 100 varieties of true taro, but in the continental U.S., you’re most likely to only come across two of them:

Dasheen (C. esculenta var. esculenta) is the variety shown throughout this post. It’s large -- shown here next to a clove of garlic (2, pictured above) -- so large that you’ll sometimes find it sold cut in smaller sections. Once cooked, its flesh is drier and more crumbly than that of eddoe. 

Eddoe (C. esculenta var. antiquorum) is smaller, ranging in size from that of a fingerling potato to that of a large lemon. They are a little blander and more moist (sorry) than the larger dasheen. 

Both types have visible rings (1, above) running down the length of the corm, and although ours is fairly smooth, both dasheen and eddoe can have a shaggy exterior. Neither type is likely to be labeled by name, but you can easily distinguish between the two visually. Recipes will often specify which type you're looking for, but if not (or if you can't find one or the other), they are similar enough in taste that most of the time you can use them interchangeably.

Where to buy & how to store
You can find taro at well-stocked grocery stores or Indian, East Asian, or Latin American markets. Choose firm specimens free from soft spots, mold, and cracks, and store them in a cool, dark spot for a few days. For most of us, a brown paper bag kept at room temperature will suffice, but a root cellar would be better if you have one.

How to prep & notes of caution
Scrub them well, put on a pair of gloves, and then remove the skin (4, above) with a paring knife or a vegetable peeler. Gloves are called for due to the presence of oxalic acid crystals, which can irritate sensitive skin. If you don’t have disposable gloves, coat your hands with cooking oil before peeling -- and remember not to touch your eyes! Once the corms are peeled, cut or slice them (3, above) as needed for your intended use, and either use immediately or place in a bowl of cold water to prevent discoloration. Smaller eddoe are often cooked with the skin on and then peeled, which eliminates the need for gloves.

Please be advised: If those oxalic acid compounds can irritate the skin on your hands, imagine what they can do to your throat: Don’t eat taro raw, it needs to be cooked first. (That goes for the leaves and leaf-stems too.)

Taro flesh color can vary from creamy white or speckled (3, far above) to pale pink and purple. Whatever color you start with, though, know that depending on the preparation, you’ll likely end up with a less appetizing shade of grayish-purple sludge once it's cooked.

When you think of taro, you’ll likely first think of poi -- the dish is popular in Hawaii and the Philippines, but it's very polarizing. In Vegetable Love, Barbara Kafka writes: "With the best will in the world, I cannot honestly give a recipe for poi, since I hate it." Poi opinions aside, taro is just as versatile as a potato and perhaps even more so. Once cooked, its sweet, nutty flavor is welcome in a wide variety of dishes, both sugary and savory. Here are a few ideas to get you started:

• Shred taro and make fritters or crispy taro pancakes. 
• Deep-fry taro to make chips or fries.
• Taro can be mashed or puréed, but heed Elizabeth Schneider's warning: "Do not plan to simply boil and purée or mash it as you would potatoes: Taro is gluey without additional baking or frying to dry, aerate, or crisp the mixture." 
• Cut taro into chunks and cook it in stews and soups. In Roots, Diane Morgan shares a recipe for Soba Noodles in Mushroom Broth with Taro and Kabocha Squash.
• Taro can be turned into a paste that is then used in baked goods like pastries and breads.
• It can even be used in desserts, like ice cream, cheesecake, and pie -- try that with a regular potato!
