Recipe Overview
Nutritional Information (per serving)
Essential Equipment Guide
Mandoline Slicer: This tool is important for achieving uniformly thin cucumber slices, which ensures even marination and presentation. Alternatives like a sharp knife can work, but may require more skill and time. Look for a mandoline with adjustable thickness settings for versatility.
Mixing Bowl: A medium-sized mixing bowl is essential for evenly combining the ingredients. Stainless steel or glass is preferable for easy cleaning and non-reactivity with acidic ingredients. Ensure the bowl is large enough to toss the salad without spilling.
Whisk: A small whisk is crucial for emulsifying the dressing, ensuring all ingredients are well combined. If a whisk is unavailable, a fork can be used but may take longer to achieve the same consistency. Choose a whisk with a comfortable handle and sturdy wires.
