Tips for buying, storing and cooking potatoes
- Potatoes should be fairly clean, firm and smooth.
- Avoid potatoes that are wrinkled or have wilted skins or soft dark surfaces; cut surfaces with a green appearance.
- Choose potatoes of uniform size for even cooking.
- Store potatoes in a cool, humid (but not wet) dark place that is well ventilated.
- The ideal temperature to store potatoes is between 7-10°C (45-50°F). At this temperature, potatoes can be stored for several weeks, however, potatoes should not be stored more than one week should the temperature be higher than previously indicated.
- Warmer temperatures also encourage potatoes to sprout and shrivel.
- Prolonged exposure to light causes potatoes to turn green and the greening causes the a bitter flavour and should be removed before cooking.
- Potatoes should not be stored in the refrigerator. If potatoes are too cold they will develop a sweet taste.
- Gently scrub potatoes with a veggie brush or cellulose sponge to clean.
- Leaving skin on the potatoes during cooking is a great way to retain a lot of the potato's nutritional benefits.
- To shorten the cooking time of potatoes, cut them in smaller pieces.
- Peeled potatoes turn brown rather quickly and should be tossed in a lemon juice mixture to retain their colour. Prolonged soaking in water is not recommended as it can result in some nutrient loss.
