INGREDIENT KNOWLEDGE

Potato

Potatoes are starch-rich tubers whose texture can range from creamy and waxy to fluffy and floury. Choosing the right type is often more important than the recipe itself.

What Is a Potato?

The potato, Solanum tuberosum, is an underground tuber. Culinary varieties differ in starch, moisture, skin thickness, flavour, and how well they hold their shape during cooking.

Main Texture Types

• Floury or high-starch: become fluffy and dry; excellent for baking, mashing, and crisp fries.
• Waxy: remain firm and moist; useful for salads, gratins, soups, and dishes requiring neat pieces.
• All-purpose: sit between the two and work across many methods.

How to Choose and Store

Choose firm potatoes without deep cuts, rot, extensive sprouting, or green skin. Store in a cool, dark, ventilated place rather than beside onions. Green areas indicate increased glycoalkaloids and should be cut away generously; heavily green or bitter potatoes are best discarded.

Preparation and Cooking

Keep cuts even for even cooking. Start potatoes in cold salted water for boiling so the centres and exteriors cook more evenly. Dry potatoes well before roasting or frying. For mash, avoid aggressive blending because rupturing too many starch cells can make the texture gluey.

Culinary Uses

Potatoes appear in European purées and gratins, Indian curries, Spanish tortillas, Latin American causa, Middle Eastern stews, Filipino soups, British pies and chips, and countless roasted, fried, boiled, baked, and braised dishes.

Pairings and Substitutions

Potato pairs with butter, cream, cheese, olive oil, garlic, onion, herbs, chilli, eggs, meat, and fish. Sweet potato, cassava, taro, parsnip, cauliflower, or other roots can substitute in some applications, but starch and moisture behaviour will differ.

Common Mistakes

• Using waxy potatoes when a fluffy mash is required.
• Overworking mashed potatoes.
• Roasting wet potatoes and expecting crisp surfaces.
• Ignoring green or bitter potatoes.
