Lotta Hot Chocolate has us going loco over cocoa. Prep here for National Hot Chocolate Day, Jan. 31. Dunk puff pastry cinnamon sticks in Mexican hot cocoa. Make and wrap up hot chocolate on a stick or hot chocolate spoons for sweet gifts. Hot chocolate floats with ice cream are pretty cool, as is “Serendipity” frozen hot chocolate. Hotties? Got those, too: s’mores, caramel, peppermint, cookies and cream, pink or red velvet, cardamom rose and mug shots of many more.
