Key Lime Pie

Key Lime Pie

I was inspired to make Key Lime Pie after watching The Great British Bake Off Series 3. In episode 5, the contestants final challenge was American Pies. This challenge produced what was called ‘the best bake of the series’: Ryan Chong’s Key Lime Pie (pictured below). Ryan struggled during baking it, but managed to turn out an absolutely beautiful pie. He was awarded star baker and praised highly by Mary and Paul. It was a very emotional moment and I was so pleased for him! He used short crust pastry for his pie, but I’ve made it a little simpler by using a biscuit base. I’ve combined digestive biscuits with ginger nuts for a hint of ginger flavour – inspired by Ryan! The filling is super zingy and I’ve topped the pie with whipped cream to set off the sour lime. If you’ve never made Key Lime Pie before, this is a great place to start!

Ryan’s original Key Lime Pie recipe can be found on the BBC website.

To make the base I used my food processor to whizz up the digestive and ginger nuts into crumbs. I mixed them with the melted butter and pressed them into a loose bottomed tart tin. Then I baked it for 10 minutes.

To make the filling, I whisked the egg yolks together, then whisked in the condensed milk with my electric hand mixer.

Then I added the juice and the zest of the limes and whisked it for a few minutes.

I poured the lime filling into the base and baked it for 15 minutes until it was set, but it still wobbled in the centre.

To decorate the Key Lime Pie I whipped up the cream with the icing sugar and the vanilla, and I piped it onto the pie. You can of course just dollop it on with a spoon. I sprinkled over some more lime zest too.

The Key Lime Pie filling is so zingy and sour, it makes your mouth tingle in such a good way! The whipped cream balances it out perfectly and the base adds crunchy texture. It’s a great summer dessert and an excellent refresher after a heavy meal. Key Lime Pie is one of those classic desserts that everyone has to try!

  1. Love your updated pics!

    I made a key lime pie the other day using oreos for the crust. I used an American recipe though, and ended up with too high a ratio of butter to biscuit in the base – it was still delicious though. This is deffo one of my fave desserts!

    Interesting too that we call it a key lime pie when we are blatantly not using key limes. Lime pie sounds so wrong though.

    Anyway, love your pics and so glad I re connected with your blog after finding you on Insta!

    1. Thank you! I’ve got a key lime pie with coconut oreo crust on here too, so I can imagine how delicious yours was! I know what you mean about the fact they’re not key limes, everyone knows the dessert as key lime pie now because it became so famous, but very few have access to the genuine key limes – I’d love to try them to see the difference. It’s great to re-connect, I remember you from when I first started blogging but I’ve not seen you around for a while. Glad to see you’re back!!
