Yes! You can foam soy milk! This post is here to inform you that it is possible. Look at those peaks!!
This is a PSA to anyone who might be into foamy coffees, lattes and London Fogs (my favorite). Get yourself one of these:
This is a hand-held, slim little battery-powered steamer that seems gimmicky in concept, but foams up soy milk like a charm. I mean, the both of us were shocked. The foam appears and stays. In that picture up there, the layer of foam starts around the middle of the butterfly.
Here’s the trick, though: “Silk” brand soy milk does not work. You need an off-brand that contains xanthan gum.
We attempted this with Silk and with our favorite generic soy milk, and the Silk went flat quickly. Xanthan gum is the key. All you need to do is heat up the milk on the stove or with your espresso steamer nozzle, get it nice and hot- not boiling. Then insert this little thing and voila!
We picked it up for $25 on Amazon. It was either that or buy some bigger contraption that took up a lot of space. This is much better.
