For a lot of us, salad dressing is fine, store-bought and carelessly shaken before application, maybe by being dropped on the floor. But if you have more discerning tastes, and prefer to blend some dressing up fresh, the Prepara Dressing Whiz can help you out.
Essentially a miniature blender, the Whiz takes two AA batteries and can whip up to 225 grams of ingredients into a nice dressing. Now if you don't have anything that needs to be actually blended, using the Prepara to stir up some liquids seems sort of like a needless extravagance, but if you want something fresh and shredded in there, it seems way easier than a blender.
To top it all off, the Whiz also doubles as a container, with a no-drip spout and an air-tight cap. If involved salad dressing wizardry is your cup of tea, you can pick a Whiz up on Amazon for $US29.99. [7Gadgets]
