Nitro-style filter coffee using an immersion blender

One [way](https://www.youtube.com/watch?v=tD_4hOg_SWU) to make a cold, nitro-style shot at home is to brew an espresso add ice, and then steam it. Although this method can produce great results, it doesn't work with filter coffee as the steaming step adds heat & water, and using ice would dilute the coffee further. A way to achieve similar results is to use an immersion blender instead. <figure class="img-half"><video class="" src="/media/articles/videos/clip-ae49929931ad.mp4" controls=""></video></figure> I've been using my metal milk pitcher to blend things while cooking (it's just the right size) and I've noticed it easily creates a very consistent vortex, the kind of vortex you're looking for when foaming milk. Can this be used to foam cold coffee as well ? turns out it works really well. The recipe is simple, brew coffee as usual, if you want it cold just put it in the fridge. When ready pour it in your pitcher and blend it with an immersion mixer. I find that going up and down at the beginning introduces a lot of air into the mix, then by putting the head of the mixer at the right angle you can create a vortex to homogenize the bubbles. That's it! just pour into a glass.  <figure class="img-half"><img class="" alt="image" src="/media/articles/images/image_0E40kzQ.webp"><figcaption>The final drink</figcaption></figure> How does it taste ? very good, although I get the feeling it mutes the taste a bit, but I would need to do a proper side-by-side comparison to be sure. The texture is really nice though. How long the foam last will depend on the coffee and how it's prepared. If you want a more stable foam you can add a small amount of xanthan gum or equivalent. I've experimented with a [nappage](https://en.wikipedia.org/wiki/Nappage) mix for baking I had at home (about 0.1g of powder in 200g of coffee) and it works really well (and has zero taste). The foam can even get too thick and needs to be agitated to mix with the liquid phase. * * * Note : James Hoffmann also discuss related techniques [here](https://www.youtube.com/watch?v=0HdzJz_evNw).
