Potatoes are a versatile staple in kitchens worldwide, but not all varieties are created equal. Understanding the differences between potato types can elevate your cooking and ensure the best results for every dish. The key to choosing the right potato lies in understanding its starch content and how it affects texture and cooking properties.
Starchy potatoes like Russets and Idahos are ideal for baking, mashing, and frying. Their high starch content creates a fluffy interior when cooked, perfect for absorbing flavors and creating smooth mashed potatoes. On the other hand, waxy potatoes such as red-skinned and fingerling varieties have lower starch levels and hold their shape better during cooking. These are excellent choices for potato salads, roasting, and boiling.
Selecting the appropriate potato variety can make a significant difference in the outcome of a recipe. For crispy fries or light, fluffy baked potatoes, high-starch options are the way to go. When making potato salads or dishes where maintaining potato shape is crucial, waxy varieties shine. By matching the potato type to the cooking method, chefs can achieve optimal texture and flavor in their potato dishes.

Buying and Storing Potatoes
Proper selection and storage of potatoes are crucial for maintaining their quality and flavor. Knowing what to look for when buying and how to store potatoes correctly ensures you’ll have the best ingredients for your dishes.
Selecting Quality Potatoes
Choose firm potatoes with smooth, unblemished skin. Avoid those with green spots, sprouts, or soft areas. Different varieties suit different dishes – russet potatoes are ideal for baking and frying, while Yukon Golds work well for mashing and roasting. Red-skinned potatoes hold their shape, making them perfect for salads and boiling. Check for cuts or bruises on the skin, as these can lead to spoilage. Select potatoes of similar size for even cooking times. Freshness is key – opt for potatoes that feel heavy for their size and have a slight earthy smell.
Storage Practices
Store potatoes in a cool, dark, and well-ventilated area. The ideal temperature range is between 45-50°F (7-10°C). Higher temperatures can cause sprouting, while lower temperatures may lead to a sweet taste and discoloration. Keep potatoes away from onions, as they release gases that speed up spoilage. Use paper bags, baskets, or cardboard boxes for storage – avoid plastic bags as they trap moisture. Do not wash potatoes before storing, as moisture promotes mold growth. Check stored potatoes regularly and remove any that show signs of spoilage to prevent it from spreading. Properly stored, potatoes can last 2-3 months.
