I have tried making pudding from recipes that have cornstarch and one with flour. Neither has the same smoothness of the cooked packaged mixes. What is the magic in the packaged mix? I am looking for a more smooth pudding recipe.
The Industrial Product
By way of example, this is the list of ingredients from Jello Vanilla Instant Pudding and Pie Filling mix (a very common brand in the US):
The ingredients that are not well known, or are that are relevant to the texture are:
What you do not see in the mix is any true dairy or egg products. The pudding is entirely a creation of these thickening agents, and the flavor only from the natural or artificial flavors (which might or might not include vanilla extract, but more likely are vanillin and other flavors).
Puddings (at least in US usage of the word) are a variant on custards, where the thickening power of eggs in a basic custard is supplemented with a starch.
It is not really possible to achieve a consistency identical to that provided by the industrial ingredients, so if you are using that as your standard, you will fail.
Still, an extremely smooth product with a delicate mouth feel (which in my personal opinion is actually superior) is possible by creating a pudding based on:
The ratio is very very approximately: 1 quart (1 liter) dairy to 6 eggs yolks to 4 tablespoons cornstarch.
These puddings can be created stove top or baked in the oven, and can be flavored in a variety of ways. In either case, you must use good technique to avoid curdling the eggs.
the thickner can be changed, I personally have trouble working with both flour and cornstarch--found this out when making gravey. Instead we use Guar Gum & Xanthan Gum. My cooking classes suggested using tapioca, pectin, gelatin, or arrowroot. quick search on wiki givea a long list.
Tradidionally arrow root is suppose to produce a shiney, smoother result but is hard to find a nd expensive. (The gums I use, we bought 8 oz packages and have been using them for over 5 years...not even 1/2 empty..and I have seen the same pacaages in the local grocrey stores near me lately)
