Mash

To mash is to crush or press cooked food into a soft, cohesive preparation. Mashing is commonly used for potatoes, root vegetables, legumes, fruit and other ingredients. The final texture can range from rustic and chunky to smooth and fine, depending on the tool and method.

Common mashing tools

• Potato masher: creates a rustic texture with some small pieces remaining.
• Fork: useful for small quantities of soft foods such as avocado or cooked vegetables.
• Potato ricer: presses cooked potatoes into fine, even pieces for a smooth purée.
• Food mill: produces a fine texture and can separate skins or fibres, depending on the disc.

How to mash potatoes successfully

Cook potatoes until tender, drain thoroughly and allow excess steam to escape. Mash or rice while hot, then incorporate warm milk, cream or butter as required by the recipe. Avoid overworking the starch, which can create a gluey texture.

Mash versus purée

Mash often retains a more rustic texture and may contain small pieces. Purée is generally smoother and more uniform, often produced with a food mill, ricer, blender or other processing equipment. The best tool depends on the ingredient and desired texture.

Chef’s tip: Avoid using a high-speed blender or food processor for starchy potatoes unless the recipe is specifically designed for it. Excessive mechanical action can release too much starch and make the result sticky.

Key distinction: Mashing breaks cooked food into a cohesive texture; it is not necessarily the same as producing a completely smooth purée.
