The primary advantage of this model lies in its composition. The product description specifies that the body is manufactured from up to 90% recycled stainless steel, specifically the 18/10 grade. This alloy designation indicates a high chromium and nickel content, which creates a passive oxide layer that protects the metal from rust and pitting. Unlike lower-grade steels or aluminum bodies that may pit when exposed to acidic ingredients, this material maintains its structural integrity over years of use. For UK home cooks, this means the pot can handle frequent cooking of tomatoes, wine, or vinegar-based sauces without the risk of metallic contamination or surface degradation.
Safety is the paramount concern in pressure cooking, and this model employs several mechanical indicators to ensure user confidence. The locking indicator changes from red to green and produces an audible “click” when the pot is securely closed. This dual-signal system provides immediate feedback that the lid is properly engaged, preventing the common error of attempting to open a pressurized vessel. The clarity of this mechanism is crucial for beginners who may be uncertain about whether the pot is sealed correctly. Unlike some models that rely on subtle visual cues, this explicit color change and sound offer a high level of assurance.
Material Integrity and Corrosion Resistance
The durability of 18/10 steel also impacts the longevity of the exterior finish. Because the material is resistant to discoloration, the pot retains its appearance even after repeated washing. The description notes that the pot is dishwasher-safe, a significant benefit for a heavy steel item. While some users prefer hand-washing to preserve finishes, the robust nature of this specific steel grade allows for the convenience of machine washing without immediate risk of dulling or staining. This makes it a practical choice for busy households where maintaining a pristine appearance is less critical than functionality, yet the material still resists the wear and tear that affects cheaper alloys.
Handling Acidic Ingredients
When cooking acidic foods, the choice of material is critical. Aluminum pressure cookers can react with acids, leading to a metallic taste and potential leaching of minerals. The 18/10 steel used in this Fissler model is non-reactive, ensuring that the flavor of the food remains pure. This is particularly relevant for recipes involving red wine reductions or long-simmered tomato stews. The stability of the steel ensures that the food retains its natural color and taste, a benefit that is often overlooked until a user compares the results from a steel pot versus a coated or aluminum one.
Longevity Over Coated Alternatives
Many modern pressure cookers rely on non-stick coatings to facilitate easy cleaning. However, these coatings can scratch or peel over time, exposing the underlying metal and potentially contaminating food. The 18/10 steel construction of this product eliminates this concern entirely. There is no coating to degrade, meaning the cooking surface remains safe and effective indefinitely. While food may stick more readily than in a non-stick pot, the durability of the steel ensures that the pot will not need replacement due to surface failure. This makes it a more sustainable option for those looking to reduce waste in their kitchen.
Safety Mechanisms and Operational Clarity
The pressure regulation is managed through a cooking indicator with two distinct levels. This allows users to select between gentle and quick cooking modes, adjusting the internal pressure accordingly. The ability to regulate pressure manually gives the cook more control over the texture of the food, which is particularly useful for delicate items that require lower pressure to prevent overcooking. The evaporation function on the handle further enhances safety by allowing the pressure to be reduced easily and safely. This feature is a critical component of the overall safety design, ensuring that the pot can be depressurized without the need for rapid cooling or complex valve manipulation.
The Locking Indicator System
The red-to-green locking indicator is a simple yet effective safety feature. It eliminates the guesswork involved in closing the lid, a common source of anxiety for new pressure cooker users. The audible “click” serves as a secondary confirmation, ensuring that the user does not miss the visual cue if they are not looking directly at the indicator. This redundancy is a thoughtful design choice that aligns with UK safety standards for pressure vessels. By providing multiple forms of feedback, the design reduces the likelihood of user error, which is the primary cause of pressure cooker accidents.
Pressure Regulation and Release
The two-level cooking indicator allows for precise control over the cooking process. Users can choose a lower pressure for gentle cooking, which is ideal for vegetables and delicate proteins, or a higher pressure for quick cooking of tough cuts of meat and legumes. The evaporation function on the handle provides a safe method for releasing pressure, allowing the user to control the rate of depressurization. This is particularly useful when cooking foods that may foam or splatter, as it allows for a gradual release rather than a sudden burst of steam. The combination of these features ensures that the cooking process is both safe and controllable.
Capacity and Heat Distribution
The 4.5-litre capacity and 22 cm diameter of this pressure cooker make it suitable for medium-sized households. This size is large enough to cook a full meal for a family of four but small enough to fit comfortably on most standard stovetops.

This compatibility means that the pot can be used on a wide range of cooking surfaces, from gas to electric to induction. The even heat distribution ensures that the food cooks uniformly, regardless of the heat source used.
Filling and Level Indicators
The level indicator from min to max is a practical feature that helps users avoid common mistakes. Overfilling a pressure cooker can block the pressure valve, leading to unsafe conditions. The clear markings on the pot allow users to fill it to the appropriate level for the type of food being cooked. This is particularly important for foods that expand during cooking, such as beans or rice. The indicator ensures that the pot is not overfilled, maintaining safety and preventing blockages. This simple feature contributes to the overall ease of use and safety of the product.
