Emulsions are the job an immersion blender does better than any other machine in a domestic kitchen, and it is the use most owners never try. A tall narrow beaker, a stick blender and thirty seconds produce mayonnaise more reliably than a bowl and a whisk. The technique is specific, though, and doing it in the wrong container is why people give up.
The beaker is the equipment
Mayonnaise works because the blade sits in a column barely wider than itself, so the oil is drawn down in a controlled trickle rather than sloshing about. A wide bowl gives the blade nothing to grip. Use the beaker that came with the blender, or any straight-sided jar the foot just fits into.
Order of ingredients
Egg and any acid go in first, oil poured on top and left to settle. Put the blender foot flat on the bottom, start it, and hold it still until the base of the mixture turns pale and thick. Only then lift slowly, drawing the remaining oil down in stages.
Choosing a wand that suits the job
A wand with a wide bell and a low-speed setting emulsifies more gently and splashes less than a narrow high-speed one, and detachable feet make washing up far quicker.

Sauces beyond mayonnaise
The same tool smooths a tomato sauce in the pan, purees roasted peppers, blends dressings that would otherwise separate and turns cooked beans into a dip. None of these need a jug blender. The advantage is that everything happens in the vessel you already cooked in.
Where emulsions go wrong
- Cold egg straight from the fridge is slower to come together.
- Lifting the blender too early breaks the emulsion.
- Too much oil at once splits it, and it will not recover by force.
- A wide bowl instead of a narrow beaker rarely works.
- Over-blending a garlic sauce turns it bitter and thin.
Safety around the blade
Unplug the blender before you swap the foot or the whisk; the trigger is not an interlock. Scrape the beaker with a spatula, never a finger, and rinse the foot under running water with a brush rather than dropping it into a sink of suds. The blade is small, close to the rim, and sharper than it looks.
Storage and food safety, briefly
Homemade mayonnaise contains raw egg, so keep it refrigerated, make small amounts and treat it as a short-life item rather than something for the back of the fridge. If anyone at the table is pregnant, elderly or unwell, use pasteurised egg or skip it, and ask a professional if you are unsure. That caveat aside, it is one of the most satisfying things a cheap appliance can do.
