The easiest way is the jar shake: pour cold milk into a lidded jar no more than a third full, shake hard for 30–60 seconds until it doubles in foam, then microwave the open jar 30 seconds to set the foam. A whisk, a French press plunger, or a fork all work too — the trick is beating in air, and warm foam holds while cold foam stays loose for iced drinks.
Recommended Shake cold milk in a jar 30–60s, then microwave 30s to set the foam — no gadget needed — Frothing is just forcing air into milk so its proteins trap bubbles, and any tool that whips vigorously does it. The jar method is the most reliable: fill a screw-lid jar no more than a third with cold milk (it needs room to expand), close it, and shake hard for 30–60 seconds until the volume roughly doubles. Take the lid off and microwave 30 seconds — the heat sets the foam so it lasts on top of coffee instead of collapsing. No jar? Heat the milk first, then whisk fast by hand, use a French press by pumping the plunger up and down a dozen times, or beat with a fork in a mug. Whole milk foams richest thanks to its fat and protein; barista oat milk is the best non-dairy foamer. For iced coffee, skip the heating and shake cold milk for loose cold foam. Don't fill the container more than a third, or it can't build a proper head.
