To my palate, this is the perfect Panna Cotta. It is lightly set and lightly sweetened with a good balance between fat and lean dairy ingredients.
Panna Cotta is a chilled, softly gelled, silky smooth, creamy, melt-in-your-mouth Italian dessert that translates as “cooked cream.” I mentally put it in the pudding and flan category because of its creamy, set quality, but unlike most flans and puddings, it usually contains no eggs (for an interesting exception to this see The Sweet Life: Desserts from Chanterelles by Kate Zuckerman). In consistency, it is somewhere between a flan and lightest possible gelatin. When set, it can be unmolded, in which case it will shimmy seductively on the plate. It’s a little bit of heavenly cool on a spoon.
Typically, Panna Cotta is made by melting softened gelatin in hot liquid, combining with a sweetened dairy product, pouring into molds, and finally chilling to set the gelatin.
Dana of TastingMenu offers a deep look at the chemistry behind this dish in her blog post titled, Perfecting Panna Cotta, which I found most interesting. I appreciate cooks who work to understand the underlying science and then use that knowledge to create dishes that are both unique and inspired.
I agree with Dana that there is no reason to actually “cook” the cream and it may change the texture of the finished dish slightly. You only need to heat enough liquid to melt the gelatin: ½ to 1 cup of very hot liquid to 1 packet of softened powdered gelatin.
I”m also intrigued by her admonition to cool the melted gelatin at room temperature for 1 hour before finishing and refrigerating the panna cotta. Dana says that this process helps to form a tighter, stronger web of protein chains, which enables you to use slightly less gelatin and achieve a soft set that does not become firmer as the days pass in the refrigerator.
However, if you don’t have an hour to wait, you must at least cool the hot gelatin gradually by adding the cold liquid to it a tablespoon at a time until the gelatin feels cool to the touch. If you rush this step, the mixture will likely be lumpy.

Typically, a ½-cup of panna cotta is one serving. It is rich, so a little goes a long way. Thus, look for curved bottom molds that hold 5-6 ounces, or glassware, ceramic ramekins, or custard cups that hold about that same amount. If you plan to unmold the panna cotta, it helps if the mold is metal (so that you can quickly get the mold hot by dipping in boiling water, which makes for a clean release of the contents) or a pliable container, such as a plastic storage container.
To develop my master recipe for panna cotta, I created a recipe grid that compares key ingredients across examples from 20+ respected cooks. The most interesting of these examples are listed under “Inspiration” at the end of this post. As you might imagine, the key proportion of gelatin to total amount of liquid is all over the place in these examples.
Some examples I encountered use so much gelatin that I suspect the author didn’t actually test the recipe or taste the results. You should not be overtly aware that there is gelatin in this dessert when you’re eating it. That aspect should be quite subtle. For my master recipe, I’m using enough gelatin to enable unmolding of the panna cotta. If you do not plan to unmold, you can use a little less.
As it may be difficult for some folks to acquire gelatin sheets (which are cool because they’re rated for gel strength), I’m working here with standard Knox powdered gelatin. If you do happen to have sheet gelatin, you’ll have to determine the substitution based on the strength of the particular type you have. For an in-depth discussion and substitution formula see eG Forums.
Panna Cotta Tips & Tricks
- 1 packet of Knox powdered gelatin = ¼ ounce = 2½ teaspoons.
- Do not use gelatin with bromelin-heavy fruits, such as fresh or frozen pineapple, guava, figs, kiwi, or gingerroot. The Bromelin enzyme destroys the protein bonds in the gelatin, thus preventing gelling. (Cooking or canning pineapple destroys the bromelin.)
- If you want to add warm, melted gelatin to a cold liquid, you must gradually cool the gelatin by incorporating the cold liquid a tablespoon at a time until the gelatin is cool. Then you can add it to the remainder of the cold liquid. If you stir melted gelatin into a cold liquid, the mixture will be lumpy.
- To achieve a silky, light texture with this master recipe, very thick dairy products, such as cream cheese or fresh goat cheese, must be thinned to about the consistency of sour cream or perhaps Greek yogurt. If the mixture is too thick, the Panna Cotta will be heavier than usual for this recipe.
