Potato is the world’s 4th largest food crop following rice, wheat, and corn. Potatoes were first cultivated in Peru and Bolivia around 8,000 BC to 5,000 BC. The Inca Indians in Peru discovered a way to dehydrate and mash the potatoes, which they could store for a long time, and hence, potatoes became staple food in Peru.
In the mid-16th century, Spanish conquered Peru. They discovered the goodness of potatoes and carried them to Europe. Due its plain look and bland taste, people in Europe did not accept it as food and started using potatoes as livestock feed. However, the farmers in Europe found it easier to grow potatoes than other crops, hence potatoes became popular food crop there as well. Gradually, it spread around the world and has become staple food in many countries. Today, potato is grown in all 50 states in the USA and more than 125 countries throughout the world.
There are many varieties of potatoes categorized into starchy, waxy, and all-purpose types:
Starchy - Starchy potatoes are high in starch, low in moisture, and do not hold their shape well after cooking. Idaho Russet and Katahdin are examples of starchy potatoes. They are good for boiling, baking, and frying, but are not recommended for dishes like potato salads and casseroles which require firm-textured potatoes.
Waxy - Waxy potatoes are low in starch and are creamy and firm. They hold their shape after cooking. Red Bliss, Inca Gold, Fingerling, and New Potatoes are a few examples of waxy potatoes. This variety is excellent for cooking dishes that require firm potatoes, such as casseroles, potato salads, and gratin and can also be used for roasting, baking, boiling, and frying.
All-purpose - These potatoes are mild in starch; the starch content is more than waxy variety and less than starchy variety. All-purpose potatoes can be used for any cooking applications. Yukon gold and purple peruvian are examples of all-purpose potato.
Due to their mildly sweet taste, potatoes can be cooked in combination with other vegetables, meats, or spices to absorb their flavors and add impart its mild-sweetness to the dishes.
When buying, look for firm and clean potatoes with no discoloration, molds, or bruises. Store potatoes in a cool, dry, and ventilated place away from sunlight. The ideal temperature for storing potatoes is 50 degrees Fahrenheit or 10 degrees Celsius. An unheated basement or closet can be ideal for storing potatoes. At this temperature, potatoes will last for months. Storing potatoes at a temperature below 50 degrees Fahrenheit will convert its starch into sugar quickly, and you will end up with sweet tasting potatoes. On the other hand, higher temperature speeds up sprouting, water loss, and less firm potatoes. It’s recommended to buy less potatoes and use them quickly if you cannot store them at or around 50 degrees Fahrenheit.
