If you love milk foam on your coffee and don't have a fancy coffee machine, this little gadget is a god-send!
Ikea sells them for $4.99. They need two batteries, I use rechargables, and this little whipper-snapper is still going strong after 4 months of daily use - without recharging.
I fill a coffee mug 1/4 full with milk, heat it for 30 seconds in the microwave and then whip away (about 25 seconds)and pour in the hot coffee on top. A beautiful French style cafe creme; almost solid foam floats 1-2 inches deep with rich dark coffee underneath. Foam lasts for 2 to 3 cups, saving many calories.
Soy Milk whips even better than milk, and I often add a dash of one of my home-made syrups (ginger and lavender work well) to the hot milk and incorporate.
It also whips whipping cream in small amounts, so no whisks or machines needed for that last piece of pumpkin pie.
