I've yet to try any brand that made a decent cup of chocolate on one package or the recommended amount per cup (Ovaltine) of hot chocolate.
I take TWO packages of any good brand per cup,AND I add a couple of teaspoons of sugar or even Equal- the fake sugar.
To make it even richer? Add cream or Cremora. Also- Instant Nescafe Coffee,makes a great combo.
Stay away from Swiss Miss...that stuff is evil. Always tastes rancid.
