Blender Mayonnaise

Making your own blender mayonnaise is a simple kitchen skill that yields far superior results to any shop-bought jar. This dairy-free staple uses a few basic larder ingredients—fresh eggs, sharp lemon juice, and Dijon mustard—to create a velvety emulsion that is both rich and bright in flavour. By using a blender, the process becomes virtually foolproof, ensuring a thick and glossy finish every time.

This versatile condiment is an essential addition to your recipe repertoire, serving as the perfect base for creamy dressings, potato salads, or as a dip for chips. Because you can control the oil used, you can opt for a light neutral vegetable oil or a fruity olive oil depending on your preference. Keep a jar in the fridge for a quick, homemade touch to your weekday lunches.

How to make Blender Mayonnaise

In a blender or food processor, blend together the egg, lemon juice, mustard, fine sea salt, and freshly ground white or black pepper, blending until well combined.
