Tip for the Soy milk drinkers out there (thats me!):
You can drink it, you can cook with it, you can bake with it, but my friends you can't make instant pudding with it. I have tried not once, but twice and failed!
I ended up with a chocolate soup and then cookies and cream soup (oreo pudding is an amazing center for a chocolate layer cake).
After my second failed attempt, I went a "google-ing". Turns out soy milk does not contain casein which is needed to make jello, well jel!
Kraft suggests using a half soy, half milk mixture. We drink Silk based on flavor and nutrition content, so using milk is fine for pudding.
So, fellow soy drinkers, if you have had instant pudding issues now you know why.
