In his book, Milkshake Monday, based on his popular TikTok series of the same name, Larry Canam shares how to enjoy three classic Neapolitan ice cream flavors in one layered milkshake. "It does take a bit of work ... but it’s totally worth it. Just look at those layers!" he writes. "You can enjoy each flavor separately, or mix them together with our straw. This is a good recipe to double the quantities and make two shakes at once."
