Can you mix instant pudding with cook and serve pudding?

No, it is not recommended to mix instant pudding with cook and serve pudding. Instant pudding is designed to be mixed with cold milk and sets quickly, while cook and serve pudding requires heating to thicken. Mixing the two types of pudding together may result in an inconsistent texture and flavor profile. It is best to follow the instructions on the packaging for each type of pudding for optimal results.
