Mandoline slicers are fundamental for anyone seeking uniform and consistent cuts, far surpassing the efficiency of manual knife skills. They act as a bridge between traditional knives and electric food processors, offering a balance of control and speed. Characterized by a flat surface intersected by a sharp blade, these tools allow vegetables to glide over, producing slices of predetermined thickness. While many models offer adjustable settings for varying slice dimensions, some are designed for a standard cut.
The majority of mandoline slicers feature durable stainless-steel blades, known for their lasting sharpness. However, alternative materials like ceramic, found in models such as the Kyocera, provide a different slicing experience. For those seeking versatility, higher-end mandolines often include a selection of interchangeable blades, allowing for specialized cuts like waffle patterns or fine julienne strips, broadening their utility in complex culinary tasks.
The Benriner Super Slicer consistently receives high praise from culinary experts. Its design emphasizes practicality and efficiency. Its lightweight plastic construction makes it maneuverable and simple to store, appealing to those with compact kitchen spaces. Unlike bulkier stainless-steel models, the Benriner features a sleek, industrial design devoid of unnecessary embellishments. A precise adjustment knob on the underside allows for exact thickness control, from ultra-thin kohlrabi slices to substantial potato planks for gratins.
During rigorous testing, the Benriner mandoline's exceptionally sharp blade demonstrated superior performance compared to other adjustable models. Its agility and precision rival the finest chef's knives, making it a preferred tool for intricate cuts. The inclusion of three distinct interchangeable blades further enhances its utility, accommodating various matchstick and julienne cutting requirements.
While the Benriner is highly effective, its hand guard is often cited as cumbersome and awkward to use, potentially undermining its primary safety function. For enhanced protection, cut-resistant gloves are a recommended alternative. Additionally, the mandoline is not dishwasher-safe and its plastic components are prone to staining, particularly when processing vibrant vegetables like carrots or beets, requiring diligent hand washing.
For individuals new to mandoline use or those prioritizing ease of use, the Oxo Large Adjustable Handheld Slicer offers an excellent entry point. This model prioritizes user-friendliness, ensuring a less intimidating slicing experience. Its ergonomic design includes a comfortable handle and a non-slip rubber foot, providing stability during operation. A generously sized hand guard offers ample protection, while a clearly marked adjustment dial provides seven thickness options in precise 0.5mm increments.
A standout feature of the Oxo slicer is its transparent slicing surface, which allows users to monitor the sliced food, preventing blockages and ensuring smooth operation. The blade's secure locking mechanism for both slicing and storage enhances safety and simplifies setup, eliminating the need for complex instructions.
The primary limitation of this mandoline is its fixed blade, which restricts it to basic slicing tasks, omitting specialized cuts like julienne or waffle patterns. While Oxo offers larger models with more functionality, this version is best suited for straightforward slicing. The blade, though sharp enough for most vegetables, may require slightly more effort for tougher produce such as sweet potatoes, indicating a minor compromise in sharpness compared to premium models.
A more compact and budget-friendly option, the Oxo Good Grips Hand-Held Slicer provides excellent performance, sharpness, and ease of use in a small package. Priced under $20, it's an ideal choice for those with limited space or who are hesitant to invest in a larger countertop model. It effortlessly handled challenging vegetables like sweet potatoes and produced immaculate slices of apples and cucumbers across all thickness settings.
The slicer's thin, sharp blade minimized tearing and snagging, a crucial advantage for smaller devices where stability is key. Its transparent body and clearly marked thickness settings contribute to its intuitive operation. An adjustable slider with a "locked" position further boosts safety, complemented by a handheld shuttle that protects fingers, making it exceptionally user-friendly.
As a cost-effective handheld slicer, this Oxo model lacks interchangeable blades, limiting its versatility. Its narrow design also means that wider produce may need to be cut down before slicing, a minor inconvenience for some users.
Mandolines are renowned for their sharp blades, and safe operation is paramount. Treating a mandoline with the same respect as a sharp chef's knife is crucial. Maintaining focus and avoiding distractions during use can prevent accidents. Counterintuitively, dull blades can be more hazardous as they require increased force, raising the risk of slippage and injury. Regular blade replacement or sharpening is therefore advisable.
While most mandolines include finger guards, some users find them awkward. A more effective alternative is the use of cut-resistant gloves, which offer superior protection while allowing for a firm grip and precise control over the produce, making the slicing process both safer and more comfortable.
For smaller items or those new to mandolines, this compact Oxo set is perfect for gentle experimentation. It includes three interchangeable attachments—a straight blade, a grater, and a microplane—which securely fit into a storage box. The straight blade excels at shaving delicate vegetables for salads. Although thickness isn't adjustable, it provides consistently fine cuts. For very small items like garlic, careful freehand slicing is often preferred over the included finger guard.
The Zyliss slicer, featuring a micro-serrated blade, offers robust performance for tougher vegetables, though it may cause tearing on softer produce. Its sturdy construction and button-activated julienne mode are commendable, making it a reliable option despite its serration's impact on delicate foods.
This all-stainless-steel slicer from Rösle stands out for its exceptional sharpness and effortless slicing. Its easy-to-clean design and lack of plastic components are significant advantages. However, its higher price point makes it a luxury item, recommended for those willing to invest in a plastic-free, high-performance tool.
The V-blade design of this Oxo model is effective but features a more complex mechanism than preferred. While robust, its thickness settings offer large, less precise increments. Despite coming with four different blades, the julienne attachments sometimes snagged produce, indicating a design flaw in their performance.
The Gramercy mandoline, while offering adjustable settings, fell short in sharpness, requiring more physical effort for clean cuts and leading to user fatigue. Its performance did not justify its price, highlighting the importance of blade quality and efficiency.
This model presented usability challenges, particularly with its collapsible handle mechanism. More critically, its blade lacked sufficient sharpness, resulting in bruised and torn vegetables rather than clean slices, making it an unsatisfactory choice.
The Swissmar mandoline proved clunky and difficult to operate, especially when changing its large, plastic-mounted blades. Achieving precise thickness adjustments was also problematic. While its blade was sharp, its overall cumbersome design made it impractical for regular use.
With a minimum setting of 1mm, this mandoline failed to produce the desired thinness and its multiple blades were not sufficiently sharp for efficient use. The inclusion of grating accessories was deemed unnecessary and less effective than dedicated graters, contributing to a bulky and underperforming design.
Designed for niche tasks like truffle shaving, the Rösle Gourmet Slicer proved too narrow for general vegetable preparation, rendering most foods incompatible with its slicing plane. Despite its sharp blade and secure adjustment, its limited utility made it impractical for everyday kitchen needs.
The Dash Safe Slice, while prioritizing finger safety through a chute design, severely limited the size of produce that could be cut. Its guillotine-like action produced oblong slices and its safety features did not outweigh its functional constraints.
This Microplane slicer raised significant safety concerns due to a julienne blade that frequently dislodged. Its blade also consistently snagged and tore food, indicating a lack of sharpness and a dangerous design flaw that makes it unsuitable for reliable use.
Despite its appealing features like easy blade swapping and automatic julienne settings, this Oxo model is significantly more expensive than top-performing alternatives. While it performed well, its high price does not justify the incremental benefits over sharper, more affordable options.
Despite its simple design and affordability, this mandoline failed to perform effectively. Produce consistently snagged and tore, and food often became trapped between the blade and the body, making it difficult to clean and inefficient in use.
Trader Joe's canned whole-kernel corn, priced at just 99 cents, is a surprisingly versatile and nutritious pantry staple. It boasts a fresh, sweet taste, often surpassing frozen varieties, and is packed with essential nutrients like magnesium, potassium, and antioxidants. This gluten-free, low-glycemic food is perfect for enhancing various dishes, from Mexican street corn salad to corn fritters, proving its worth as an affordable and healthy option for any kitchen.
