There are two basic kinds of pudding mix – “instant” and the kind you have to cook. Busy families might prefer “instant” since it’s ready to eat in 5 minutes. The “cook and serve” pudding is also very good, but it takes about 20 minutes to cook.
You can use sugar-free pudding if you want to. Sugar adds sweetness, but offers no health benefit. The key to eating sugary food is balance – eat one serving, not the entire recipe.
