Milk frothers are an underappreciated tool

Little battery-powered milk frothers are super useful, and underappreciated. Our top uses:

1. Quickly aerating red wine so you can drink it without waiting around for it to open up in a decanter.
2. Breaking up all the lumps in matcha without resorting to your thumb after a normal whisk proves insufficient.
3. Making a flaxseed egg replacer - the whisking helps it get nice and thick.
4. Hot chocolate - first breaking up the lumps with a it of hot nondairy milk, then frothing the top once it's all mixed
