What potatoes are not good for mashing?

Certain types of potatoes are less suitable for mashing due to their starch content and texture. Potatoes with high starch content tend to absorb more moisture and result in a gluey or gummy texture when mashed. Here are types of potatoes that are generally considered less ideal for mashing:

  1. Russet Potatoes: While Russet potatoes are excellent for baking and frying, their high starch content can lead to a light and fluffy mashed texture that some may find too dry or mealy.
  2. Baking Potatoes: Varieties like Idaho or Burbank, commonly used for baking, have a high starch content. While they can be mashed, the result may be fluffier and less creamy compared to waxy potatoes.

For optimal mashed potatoes, consider using varieties with lower starch content and a higher moisture content, known as waxy potatoes. Examples include:

  1. Yukon Gold Potatoes: Known for their creamy texture and buttery flavor, Yukon Gold potatoes are a popular choice for mashed potatoes.
  2. Red Potatoes: With a waxy texture, red potatoes hold their shape well and can be mashed to a creamy consistency.
  3. Fingerling Potatoes: These small, elongated potatoes have a waxy texture, making them suitable for mashing without becoming overly starchy.

Ultimately, personal preference plays a role, and some individuals may enjoy the texture of mashed potatoes made with high-starch varieties. Experimenting with different potato types can help you find the perfect match for your preferred mashed potato consistency.
