Can you help me get my cream pie filling stiff enough?

My coconut cream pie recipe uses milk (2 cups, whole milk gives a creamier flavour), 6 eggs, 1 cup sugar, and 2 tablespoons of gelatin (and coconut of course). It doesn't go like jelly, it has more of a silky consistency.

You divide the milk thusly:

• 2/3 cup, sprinkled with the gelatin, whisked, and left to soften for 5 mins
• 1 1/3 cup to make the 'custard'

Once the custard is made (i.e. sugar whisked into egg yolks, hot milk poured in after tempering), simply whisk in the gelatinised milk. My recipe then calls for cream and the egg whites to be folded in (after cooling) to lighten the whole thing.

Most cream pie recipes that I have used call for corn starch. Flour is sometimes used but it seems to be in older recipes and the texture turns out a bit different than you would expect in a cream pie.

The yolk enzyme does have to be deactivated but this is not a big deal. After you add the starch, according to the recipe, bring the mixture to a simmer for a few minutes. The corn starch can take it and won't break just from that. I have had pies not turn out from not cooking them long enough- I've never had one cooked too long.

Using whole milk does make a difference. A little bit of milk fat adds a lot to the texture and consistency of the custard. You can successfully make the pie with lower fat milk but it will be creamier and thicker with more fat (as you would expect).

As for tapioca starch... One Thanksgiving I ran out of corn starch. I looked through my cupboard and all I had was tapioca starch that I had used for an oriental recipe. I substituted one to one.

Tapioca starch sets nothing like cornstarch. Where corn starch sets up like a creamy pudding, tapioca starch has an amusing rubbery quality to it. When I sliced the pie the knife would go almost to the bottom of the pan before the custard would slice and spring back up. I could hold up a slice of pie by the back crust and the entire slice would stretch about two feet and dangle in the air.

The pie was delicious but I didn't think it should be served to guests. :) I don't recommend using tapioca starch unless you are going for silly.

There are two styles of coconut pie, one of which has 2 variants.

One version is a true custard pie filling that is poured into the raw crust and baked as one in the oven which sets the custard.

The other style is NOT a custard, but commonly mislabeled because the ingredients are much the same. A "Cream Pie" can either have flour, cornstarch, or gelatin as a thickener. This can complicate matters seeing as how flour and cornstarch thicken when brought to a certain temperature, but gelatin thickens once it cools below a certain temperature.

Regardless, the texture of the second style is much less firm than the baked custard style. In the States, it would be similar to a "dessert pudding" (not to be confused with any of the savoury or bread puddings Europe has to offer) like Jell-O brand chocolate or vanilla pudding. Furthermore, this second style should be topped so that the "pudding skin" doesn't form on the top of the filling (unless desired).

The 2 variants in topping I mentioned earlier are whipped cream and marshmallow meringue.

I personally prefer the second style with the first variant, Young Thai Coconut Cream Pie w/a gelatin stabilized (for height and to prevent moisture weeping) whipped cream topping sprinkled w/ slivered almond & toasted unsweet shredded coconut.

The Joy of Cooking cookbooks, regardless of year, have some of the best, classical French based building block recipes and knowledge of any publicly available cookbooks I've personally ever owned. They explain the base recipe, method and technique for an unreasonable number of known dishes worldwide, and give you the knowledge to adapt any of the recipes to suit your own flavor or needs. It's my go to for any new culinary ground. Good Luck.

The best coconut cream pie, or any cream pie recipe, is in Joy of Cooking and uses flour for thickening. Makes fab pudding, too. I also (carefully) use whole eggs instead of the called for yolks for firmness. I've made this\these recipes for around 55 years, all flavors (made up flavors, too,) at home and in restaurants (for the big bucks ?) and it always disappears into appreciative faces.

I concur with the Joy of Cooking cookbook as the un-variable recipe that it is. My most recent coconut cream pie ended up "broke" as I believe I let it boil past the 2 minute mark called for, then let this filling rest in the pan while I made the meringue. Additionally, possibly the added 350° oven bake to cook the meringue topping for 15mins was too long and added too much heat further causing it to breakdown the cornstarch thickener. The result, even after chilling, was a weepy and watery cream filling -- I served it as "Coconut Floating Island" in sauce dishes!... everyone enjoyed it anyway (probably partly because of real Cream of Coconut that the recipe called for, too.)

Corn starch always works. It stiffens the pie
