SUGAR-NICE SQUARES: To be honest, you don't need to wait for a rainy day to enjoy the marshmallow, and a cup of hot chocolate, and to support a local LA treat shop. But now that our January weather is January weather-fying, and vacation-like days may be on vacation, we're thinking of the Little Flower Candy Co. of Pasadena. The oh-so-local Little Flower specializes in marshmallows and caramels. We should mention *flavored* marshmallows, like Coffee and Vanilla. Such the nice hostess gift, but a great gift for you, too. COCOA UP: You can visit the Little Flower store, or you can order online. A quarter pound of Cinnamon Marshmallows is $6.
