What is potato starch and how is it used?
Potato starch is a versatile ingredient that may not be as well known as its counterpart, cornstarch. Derived from potatoes and having a similar powdery appearance, potato starch is commonly used in several culinary applications. It serves as a thickening agent in sauces and soups, acts as a batter for fried and baked goods, and is a critical component in many gluten-free baking projects (via Bakerpedia).
The history of potato starch
Potato starch has a long history, dating back to the 17th century in Europe. Farmers first extracted starch from potatoes for laundry purposes, while the wealthy used it as a powder for wigs and facial beauty routines. Over time, potato starch found its way into the culinary world due to its tastelessness, making it suitable for a wide range of cuisines. Despite its lack of nutritional value, potato starch offers a number of unique benefits that make it a valuable addition to your pantry, either alongside or as a substitute for cornstarch (via Bob’s Red Mill).
Why choose potato starch over cornstarch?
Potato starch has several characteristics that set it apart from cornstarch, according to Bob’s Red Mill. First, it can withstand higher temperatures, making it more suitable for baking applications. When incorporated into baked goods, potato starch acts as a binding agent, resulting in a moist and chewy texture. In addition, potato starch helps prevent liquid separation, making it ideal for dishes that will be chilled before consumption (via Yummy). It also gives sauces and liquids a glossy, silky sheen for an appealing appearance.
Versatile uses for potato starch
In addition to its role in gluten-free baking, where it is often used alongside other gluten-free flours and starches, potato starch has many uses in the kitchen. Here are some ways to make the most of this versatile ingredient:
- Thicken sauces and stews: Potato starch can be used as a reliable thickening agent for sauces, gravies and stews. Its ability to create a smooth and consistent texture makes it a popular choice among chefs and home cooks alike.
- Dredging meat and vegetables: When used as a batter before frying, potato starch adds a crispy crust to meats and vegetables. It is an alternative to flour and produces delicious results.
- Puddings and fillings: Replace flour with potato starch in pudding recipes or use as a thickener in cake and pie fillings. Its neutral taste and excellent thickening properties improve the texture of these desserts.
- Perfect scrambled eggs: Celebrity chef J. Kenji López-Alt swears by potato starch as the secret ingredient for fluffy scrambled eggs. Adding a small amount of potato starch to beaten eggs results in a light and airy texture.
Bottom line
Potato starch is a valuable ingredient in the culinary world, providing thickening properties, improving texture and adding a glossy finish to sauces and liquids. Its versatility extends beyond gluten-free baking, making it a useful addition to any kitchen.
