Ratte Potato : French Fingerling Potato Variety

The Ratte potato, a French fingerling variety, is celebrated for its firm, buttery texture and nutty flavor. If you’ve ever wondered what makes chefs and home cooks seek out this specific tuber, you’re in the right place. This article covers everything from its history to how you can grow and cook it.

Ratte Potato

Often called the “queen of potatoes,” the Ratte potato holds a special place in the culinary world. Its unique characteristics set it apart from common russet or Yukon Gold potatoes. Understanding what makes it different helps you appreciate its value in the kitchen.

Origin And History

The Ratte potato’s story begins in late 19th century France. A farmer named Monsieur Joseph de Caroudel is credited with its development. He aimed to create a potato with exceptional taste and texture, and he succeeded.

Its popularity grew slowly but steadily throughout France. For decades, it remained a regional specialty, prized by those who knew of it. It wasn’t until the late 20th century that its fame spread internationally, largely thanks to top chefs championing its qualities.

Physical Characteristics And Flavor Profile

You can identify a Ratte potato by its distinct shape and appearance. Knowing what to look for ensures you get the real thing.

  • Shape and Size: It is a fingerling potato, meaning it is small and finger-shaped, typically 2 to 4 inches long. They are often slightly curved.
  • Skin and Flesh: The skin is thin, yellow, and netted. The interior flesh is a firm, yellow color that holds its shape well during cooking.
  • Texture and Taste: This is where the Ratte shines. When cooked, it has a dense, waxy, and incredibly smooth texture. The flavor is distinctly nutty and buttery, often described as reminiscent of chestnuts.

Nutritional Information

Like most potatoes, Rattes are a good source of energy and nutrients. They offer a healthy addition to your diet when prepared properly.

  • They are a good source of Vitamin C and potassium.
  • They provide dietary fiber, especially when consumed with the skin on.
  • They are naturally fat-free and cholesterol-free.
  • Their complex carbohydrates offer sustained energy realise.

Growing Ratte Potatoes

You might be tempted to grow your own Ratte potatoes after tasting them. They require a bit more attention than some common varieties, but the reward is well worth the effort.

Climate And Soil Requirements

Ratte potatoes thrive in specific conditions that mimic their French origins. Getting these basics right is key to a successful harvest.

  • Climate: They prefer cooler growing conditions with consistent moisture. They do well in temperate climates and are not suited to extreme heat.
  • Soil: Well-draining, loose, and slightly acidic soil is ideal. Heavy clay soil can hinder tuber development. Adding compost improves soil structure and fertility.
  • Sunlight: Plant them in a location that receives full sun for at least six to eight hours a day.

Planting Process

Follow these steps to plant your Ratte potato seeds, which are actually small seed potatoes.

  1. Source Seed Potatoes: Always use certified disease-free seed potatoes from a reputable supplier. Do not use potatoes from the grocery store.
  2. Chitting: About 4-6 weeks before planting, place the seed potatoes in a cool, bright spot to encourage sturdy sprout growth.
  3. Planting Time: Plant in early spring, once the danger of a hard frost has passed and soil temperatures reach around 45°F (7°C).
  4. Planting Method: Plant seed potatoes about 3 inches deep and 12 inches apart, with rows spaced 2-3 feet apart. Ensure the sprouts are facing upward.

Care And Maintenance

Ongoing care is straightforward but crucial for healthy plants and a good yield.

  • Hilling: As the plants grow to about 6 inches tall, mound soil around the stems. This protects developing tubers from sunlight and supports the plant. Repeat hilling every few weeks.
  • Watering: Provide about 1-2 inches of water per week. Consistent moisture is vital, especially during tuber formation. Avoid overhead watering to reduce disease risk.
  • Fertilizing: Use a balanced, low-nitrogen fertilizer at planting. Too much nitrogen encourages leafy growth at the expense of the tubers.
  • Weeding: Keep the area weed-free to reduce competition for nutrients and water.

Harvesting And Storage

Knowing when and how to harvest ensures your potatoes store well and mantain their quality.

Harvest “new” Ratte potatoes about 2-3 weeks after the plants finish flowering. For mature potatoes, wait until the plant foliage has yellowed and died back completely.

Use a garden fork to gently loosen the soil and lift the tubers. Be careful not to pierce or bruise them. Brush off excess soil but do not wash them before storage.

For storage, cure the potatoes in a dark, well-ventilated place at about 50-60°F for 10-14 days. After curing, store them in a cool, dark, and humid location. Properly stored, they can last for several months.

Buying And Selecting Ratte Potatoes

Since they are a specialty item, you need to know where to find them and how to choose the best ones.

Where To Find Them

You typically won’t find Ratte potatoes at every standard grocery store. Look for them at:

  • Farmers’ markets, especially during late summer and fall.
  • Specialty food stores or high-end grocery chains.
  • Online gourmet food retailers who ship produce.
  • Local farms that grow specialty vegetable varieties.

Selection And Storage Tips

Once you find a source, follow these tips to ensure you get the best quality.

  • Selection: Choose firm potatoes with smooth, unblemished skin. Avoid any that are soft, sprouting, or have green patches (which indicate solanine, a natural toxin).
  • Quantity: They are often sold in smaller nets or baskets due to their premium price. Buy only what you need for the near future.
  • Home Storage: Store them in a paper bag or a well-ventilated basket in a cool, dark, and dry place. Do not refrigerate them, as cold temperatures convert their starch to sugar and alter their flavor and cooking properties. A pantry or cellar is ideal.

Common Questions About Ratte Potatoes

What Is The Difference Between A Ratte Potato And A Fingerling Potato?

“Fingerling” is a category of potato characterized by its small, finger-like shape. The Ratte potato is a specific cultivar *within* the fingerling category. So, all Rattes are fingerlings, but not all fingerlings are Rattes. Other fingerling types include Russian Banana and Purple Peruvian.

Can I Substitute Ratte Potatoes With Another Variety?

You can, but the results will be different. The closest substitutes are other waxy fingerling potatoes like Russian Banana or Austrian Crescent. For general purposes, Yukon Gold potatoes can work in some dishes, but they are less firm and have a milder, less nutty flavor than the Ratte potato.

Why Are Ratte Potatoes More Expensive?

Several factors contribute to their higher cost. They have a lower yield per plant compared to commercial varieties. They are also more delicate to harvest and transport due to their thin skin. Their specific growing requirements and status as a gourmet, heirloom product also command a premium price in the market.

Are Ratte Potatoes Good For Mashed Potatoes?

They can be used for mashed potatoes, but they will produce a denser, less fluffy result than starchy potatoes like Russets. If you prefer a very smooth, buttery mash with a rich flavor, they are an excellent, though expensive, choice. For classic fluffy mashed potatoes, a different variety is usually recommended.

How Do You Pronounce “Ratte”?

It is pronounced similarly to “rat,” but the final “e” is soft. The common anglicized pronunciation is “rat,” while the closer French pronunciation is “raht.” Either is generally accepted when you are discussing this potato.
