Millions of people living in the tropics eat taro or Colocasia Esculenta, but I wasn't aware that Icarians (they of the famed Blue Zone) also do.
In fact, they credit taro with helping them survive World War II. In occupied territories, the Nazis commandeered most of the food and the locals were often left to starve. Thankfully they didn't know about taro and edible weeds...
Taro can be roasted whole (skin on) after washing with a scrubbing brush, similar to sweet potato & potato. It has a mild flavour which is enhanced by roasting in olive oil and lemon juice. Oregano and/or thyme, or any other herb you like to use on roast potatoes, will suit.
It is a good source of dietary fibre (5.1g/100g), Vitamin E (2.9mg/100g), Vitamin B6 (0.3mg/100g) and Manganese (0.4mg/100g).
For an adult female, this represents approximately...
20% of your adequate fibre intake
40% of your adequate Vit E intake
20% of your recommended Vit B6 intake, and
8% of your adequate manganese intake.
So next time you see some taro root for sale, pick some up and put them with your roast. Variety is the spice of life!
