honey-roasted plum mousse


They’re the underdog in this stone fruit game and I refuse (REFUSE!) to enter September without them.

Thankfully the farmer’s markets here are brimming with them, so it looks like we can go ahead as scheduled. But whew. That was close.


Everyone’s all a-chatter right now about “finding the perfect peach” and “aren’t they so good”. Blah blah blah.

Okay, I like a perfect peach as much as the next girl, BUT. I love a perfect plum so much more.

And PLUOTS! If I could go back and marry the person who first told a plum and an apricot to get a room….I would. Sorry husband. #truthhurts.


Plums sometimes get lost in the end-of-summer early-fall shuffle, so I try to be conscientious about giving them some spotlight time every year.

Today they’re shining bright like a diamond in this honey-roasted plum mousse!

Think light, fluffy, rich, juicy, sweet, tart, everything-you-want-late-summer-to-taste-like.

But better.


Basically, a stint in the oven helps dry the plums out a bit and concentrate their flavor. Then, they’re folded into an Italian meringue along with whipped heavy cream and left to chill in the fridge overnight. The next day, top with whipped cream for daintiness. And make sure to revel a bit in all the plum glory.

Honey-Roasted Plum Mousse
Sweet tart and juicy describes this honey-roasted plum mousse perfectly! Roasted plum puree gets combined with an Italian meringue and heavy cream to make this decadent dessert.
Yield: 8 servings
  • 3 red plums, halved and pitted
  • 2 tbsp (40 g) honey
  • 3 sprigs fresh thyme
  • 3 large egg whites
  • ⅔ cup (130 g) sugar
  • pinch of cream of tartar
  • 2 tbsp (30 g) water
  • 1 cup (240 g) heavy cream, divided
  1. Heat oven to 300F.
  2. Place the plum halves in a shallow baking dish, cut side up. Drizzle with honey and top with the thyme sprigs. Roast for 30-35 minutes, or until the plums are soft and have started to release their juice.
  3. Remove the thyme sprigs and blend the plums in a food processor, along with any liquid they have released. Blend until very smooth. Pour through a fine-mesh sieve, pressing on the solids so that they liquids pass through. Discard the solids. Measure out 1 cup of the puree and set aside. Reserve extra puree for another use.
  4. In the bowl of a stand mixer fitted with the whisk attachment, combine the egg whites, 1 tbsp of sugar, and cream of tartar. Whisk to combine. Mix on low.
  5. Meanwhile, pour the remaining sugar and water in a small saucepan. Stir until the sugar is well-moistened. Heat over medium heat until the sugar is melted and begins to bubble. Once the sugar has reached a rolling boil, increase the mixer speed to medium. Cook the sugar until the sugar reaches 250F. Increase the mixer speed to medium-high. Carefully pour the hot sugar into the stand mixer bowl while the mixer is still running. Increase the mixer speed to high and whip until cool to the touch, about 4-5 minutes.
  6. Meanwhile, in a second bowl, whip ½ cup of heavy cream until medium firm peaks form.
  7. Put the meringue in a large mixing bowl and gently fold in the plum puree until streaky. Fold in a third of the whipped cream and fold until combined but still streaky. Add another third and fold until just combined. Add the final third and fold until no streaks remain.
  8. Pour the mixture into a serving container and chill until set, at least 2 hours or overnight.
  9. To serve, whip the remaining heavy cream until medium stiff peaks form. Top mousse with freshly whipped cream.

    Can you believe I haven’t eaten a plum or a pluot the entire summer?!! I had better make up for lost time and get them while the getting’s good, slash make all the mousseseses out of them! Seriously, this is such a genius idea. The plums, though!

  16. Love the sound of this roasted plum mousse!

  17. Hotly Spiced says:

    Maybe it’s because they’re about the last of the stone fruits to hit the shelves. And I think commercially grown they can be dry and bitter but if you can get them from the Farmers Market and find organic plums, they’re incredibly good. My auntie in NZ grows them in her orchard and they are so much better than any you buy in the supermarket – a very different taste xx

  18. Kate says:

    It’s plum season at our farmer’s markets too. And pluots. I bought so many pluots this week!

  19. LOVE this! And I totally thought that pluots were called “plutos” the first time I saw them years ago and it made me love them even more! LMAO

  20. I am counting down the days till plum season!

  21. cheri says:

    plums are so perfect right now, but a mousse …….so clever!!

  22. So pretty – Joanne – and sounds so delicious.

  23. I’m pretty free and easy with my stone fruit. I happily confess to loving peaches AND plums AND apricots AND nectarines and basically want to eat as many of all of them as possible.

    I also love mousse, so this is my sort of dessert 😀

  24. Beth says:

    I have to admit that I’m one of those people who overlook plums. (Sorry.) After reading your post, no more! I’m on the search for the perfect plum, effective immediately.

  26. I have never seen plum mousse before but this sounds super awesome. I need to get my plump game on 🙂
