Don't have steam ? pick up a Nanofoamer.
I had started with the original Version 2 Nanofoamer, then upgraded to the Lithium. Having mastered the technique, these nanofoamers deliver textured milk to rival any good steamed textured milk on an espresso machine, and leave impressive results in the cup. Most recently I purchased the company's 'Subscale' digital scales dosing cup. With all their products, well designed, work well and elegantly packed. The Nanofoamer is pared with my 9Barista for on the go.
