The Core Ingredients of Potato Gems
At their heart, potato gems are a straightforward product built on a foundation of humble potatoes. While the exact recipe can differ slightly between commercial brands and homemade versions, the essential components remain consistent. A simple glance at the ingredient list of a popular brand like Birds Eye confirms the primary makeup: potatoes, canola oil, corn starch, salt, and dextrose.
The Foundation: The Potato
As their name suggests, the star of the show is the potato, often making up around 88% of the product. The specific variety of potato used can vary, but starchy potatoes are typically preferred because they break down easily and contribute to the fluffy interior texture. For commercial production, potatoes are first cleaned, par-boiled, and then shredded or grated into a uniform consistency. This processing step is crucial for achieving the classic nugget shape and ensuring a consistent cook.
The Binders and Seasonings
To hold the grated potato shreds together, binding agents are added. These help prevent the gems from falling apart during cooking and contribute to the crispy exterior. Corn starch is a common commercial binder, providing structure and crispiness without compromising the potato flavour. For homemade versions, a small amount of flour or even the potato's natural starch is enough to create cohesion.
Seasonings provide the flavour that makes potato gems so addictive. At a minimum, salt is used to enhance the taste. In commercial products, dextrose (a type of sugar derived from maize) is frequently added, which serves a dual purpose: it aids in browning during cooking and can enhance the savoury flavour profile. Homemade recipes often incorporate additional spices like garlic powder, onion powder, and dried herbs such as oregano to add a more complex, savoury depth.
The Cooking Medium: Oil
The final critical ingredient is the oil, which is used for both cooking and as a component within the gem mixture. Commercial potato gems are typically pre-cooked or flash-fried in a vegetable oil like canola or soybean oil before being frozen. This initial frying is what gives them their signature golden-brown colour and crunchy coating once they are cooked by the consumer. For homemade recipes, the cook chooses the oil, which can be used for deep frying, shallow frying, or air frying.
Commercial vs. Homemade Potato Gems: A Comparison
While both offer a delicious potato snack, there are key differences in the ingredients and characteristics of store-bought versus homemade potato gems.
| Feature | Commercial Potato Gems | Homemade Potato Gems |
|---|---|---|
| Main Ingredient | Uniformly shredded, pre-cooked potatoes | Grated, par-boiled potatoes (often with skin for extra fibre) |
| Binders | Corn starch, dextrose | Plain flour, corn starch, or natural potato starch |
| Seasoning | Salt, dextrose, and sometimes natural/artificial flavours | Salt, pepper, onion powder, garlic powder, herbs |
| Oil | Used for pre-frying (canola, soybean) | Used for cooking (frying or baking) |
| Consistency | Highly consistent, uniform shape and texture | Rustic, slightly irregular shapes with a more distinct potato flavour |
| Preparation | Cook from frozen (oven, deep-fryer, air-fryer) | Par-boil, grate, mix, shape, freeze, then cook |
The Journey: From Spud to Snack
Making potato gems, whether in a factory or your home kitchen, follows a similar process. First, the potatoes are prepared—par-boiled and then grated. Next, the grated potato is combined with the binders and seasonings. This mixture is then formed into the small, cylindrical or nugget shapes that are so recognisable. At home, this can be done manually with wet hands. Commercially, machinery is used to create perfectly consistent shapes. Before cooking, it's often helpful to chill the formed gems, which helps them hold their shape. Finally, they are cooked. Commercial versions are typically flash-fried before freezing for stability, while homemade gems are fried or baked until golden and crispy.
Making Your Own Potato Gems
Creating a batch of potato gems at home is a rewarding process that gives you full control over the ingredients. The process is simple and results in a snack that is often fresher-tasting than store-bought varieties.
- Prepare the potatoes: Par-boil your potatoes until they are nearly tender but not mushy. This step is crucial for achieving the soft, fluffy interior.
- Grate and combine: Once cooled, grate the potatoes into a bowl. Add binders like flour or cornstarch, and your chosen seasonings. Popular options include salt, onion powder, and garlic powder.
- Shape the gems: Form the mixture into small, tight cylinders or nuggets using your hands. Using slightly damp hands can prevent the potato from sticking.
- Chill before cooking: Place the shaped gems on a tray and put them in the freezer for about 15-20 minutes. This helps them maintain their shape when they hit the hot oil.
- Cook until golden: You can either deep-fry, shallow-fry, or air-fry your potato gems. Cook them in batches until they are golden brown and crispy on the outside. Drain on paper towels and sprinkle with a little extra salt while hot.

Conclusion: The Simple Formula Behind a Crispy Classic
Whether purchased frozen from a store or made from scratch, potato gems owe their existence to a simple but effective combination of ingredients: processed potatoes, binders, seasonings, and oil. The synergy of these components results in a beloved snack that's crunchy on the outside and fluffy on the inside. Understanding what goes into them not only offers insight into a classic comfort food but also empowers home cooks to create their own delicious, customised versions with a fresh and personal touch.
