Operating Instructions
General Use
The MasterClass Acero Mezzaluna is designed for efficient chopping and mincing of herbs, garlic, onions, and other small ingredients. It can also be used for slicing baked goods like flapjacks, brownies, and shortbread.
Chopping Technique
- Place the ingredients to be chopped on a stable cutting board.
- Grip both ergonomic handles firmly.
- Use a rocking motion to chop the ingredients. The curved blade allows for continuous contact with the cutting surface, making chopping quick and effective.
- For finer mincing, gather the ingredients into a pile and continue the rocking motion until desired consistency is achieved.
