Making homemade mayonnaise couldn’t be easier with the Kilner Mayonnaise and Sauce Jar set. Simply fill the jar base with egg yolk, lemon juice, mustard salt and pepper, then place the mesh plunger and oil dish inside the jar and tighten with the screw band. Drizzle oil into the oil dish whilst moving the plunger up and down. After about 3 to 4 minutes the consistency will be ready to serve. Other sauces such as Aioli and salad dressing can also be created using this handy kitchen gadget. The set includes a 2 piece sealing lid to store your homemade creations.
