These key lime possets couldn’t be easier to make, yet look and sound elegantly complicated. Super creamy with a refreshing lime twist. A British classic and a crowd pleaser.

You guys are in for a real treat today!  I’m so happy to introduce you to my good friend Lisa, who blogs over at Sweet2Eat Baking! 

I met Lisa (virtually) a little over a year ago, and she has to be one of the sweetest, most generous ladies I know.  Right off the bat, she was offering to help me learn the tech side of blogging, and it didn’t take long before I recognized her amazing talent and hired her to build this here blog for me, from the ground up.  She’s all the way on the other side of the Atlantic (in the U.K.), and we were able to communicate through Facebook to help bring Baking a Moment to life.  Since then, my blog has run like a well-oiled machine, which is a true testament to her attention to detail and mastery.  I can truly say that Baking a Moment could not be what it is if it wasn’t for Lisa!

So I’m handing things over to her today, as she has generously offered to share this treat with my readers while I get things back in order after several weeks of sheer insanity 9 days of travel.  So, without any further ado, here’s Lisa! 

Well hellooooo Allie fans! *waves* I’m Lisa, a British mum of 3 girly girls, and a giant man-baby. I’m the author/photographer over at Sweet 2 Eat Baking. I blog about baking, desserts and generally anything sweet to eat (hence the blog name. 😉 )

I’m so excited to be guest posting here on Baking a Moment for Allie while she’s away enjoying herself. I’mma jealous mucho!

I met Allie about a year and a half ago when she stopped by my blog with the sweet comments she leaves. I was stunned and in awe with all of her beautiful photographed goodies, and we quickly became friends. In fact, I designed this here little blog for her which was a great excuse to chat with her and ramble away! 🙂

And now you all get to put up with my rambling! Yay for you, LOL.

I’m a typical tea-loving British girl, but I’m not BFFs with Prince William, don’t live in London, don’t talk like a cockney aristocrat, and certainly do not have a stiff upper lip!

I am, however, a mahoosive fan of British desserts. And I’m inviting you all today to join me in my quest to get these wonderful British desserts more well known, because they are ‘terrific’, governor! (sorry, couldn’t resist that one).

And today, I’m sharing a classic posset with a twist, a key limey twist. 😉

I can hear you all screaming ‘what is a posset?’ Let me explain, a posset is like a pudding but oh so much better. A posset is made with double (heavy) cream, sugar, and the juice of a fruit — usually lemons. It is cooked gently until the sugar dissolves so it sets. The texture of a posset is amazing – so silky smooth and rich too. And did I mention they’re divine too? *toot toot*

This key lime posset is ridiculously easy to make, immensely creamy with a refreshing tart twist from the key limes, and textured with the zest of the limes too. Totally optional, but amps up the flavour even more.

Possets are sweet too, so if you’re crazy and sugar-fuelled like moi, you’ll love these.

Go on, give them a try!

Prep Time: 10 minutes
Cook Time: 5 minutes

Total Time: 3 hours 15 minutes
These key lime possets couldn't be easier to make, yet look and sound elegantly complicated. Super creamy with a refreshing lime twist. A British classic and a crowd pleaser.


  • 600 ml double (heavy) cream, (2 3/4 cup + 2 tbsp )
  • 200 g caster (fine) sugar, (1 cup)
  • 75 ml key lime juice, (1/4 cup + 1 tbsp)
  • zest of 3 key limes, (optional)


  • Pour the sugar and cream into a large saucepan and gently heat, stirring continuously, until the sugar has fully dissolved, then simmer for 1 minute.
  • Remove from the heat then immediately stir in the key lime juice and the zest, if using.
  • Divide the mixture between ramekins or small bowls, and allow to come to room temperature before covering with plastic wrap and transferring to the fridge.
  • Allow to chill for at least 3 hours, or up to 24 hours.
  • Serve on it's own, or with complimentary fruits such as blueberries or raspberries.


If you cannot find key limes, regular limes will be fine.
