I just made one of the best batches of chocolate chip cookies I have ever made using a combo of about 1.5 cups of Callebaut callets and about 1 cup of Guittard chips. The chocolate was so much smoother than Nestle's and a bit boozy tasting too!
I bought the Callebaut at a place in Pittsburgh when I was visiting my husband's family. They don't always have the callets, usually they just have larger chunks that would be a lot more awkward to use in cookies and its a 4 hour drive so I would like to find a place that is closer that carries them. Does anyone know of a place near Silver Spring, MD? Or is there a convenient place to order them from?
