There seems to be a pattern emerging here. It was my friend Jenny’s birthday and I wanted to bake something special for her. When I asked what she would like her immediate response was ‘Key Lime Pie’. Your wish is my command.
I’ve never had Key Lime Pie before but I immediately thought of the Hummingbird Bakery recipe that I had gazed at longingly many a time but had thought it was too complicated and messy to attempt. I would not let my niggling doubts defeat me.
I knew that I would need a bit of time to prepare this one in order to bring it to work to celebrate Jenny’s birthday in style. I got up extra early the day before to smash up digestive biscuits. It’s days like these that I wish I had a food processor. Chris had to ask me nicely to stop hammering the biscuits with the rolling pin as it was simply too early. I ran out of digestives and supplemented the rest with rich teas instead. (that’s ok right?!)
Again I had to shield my eyes from the flying digestive debris when I blitzed the shards with the hand blender. I may, or may not, have gone to work with crumbs in my hair. (It’s hard to tell with my curly mop sometimes).
I melted the butter in the microwave successfully not causing any fireworks this time and quickly stirred it all together. I quickly realised as I attempted to press the buttery biscuit paste into my flan dish that if I used all of the biscuits as instructed in the recipe that there simply wouldn’t be any space for limes in the pie…
I had felt a bit guilty and frivoulous for buying mini pie dishes recently, but this Key Lime Pie emergency meant that I got to christen them! My sleepy brain missed a step in the recipe which said you bake the biscuit base and I assumed they would need to set in the fridge (hence the extra early preparations). Into the fridge they went to wait for me upon my return from work.
I realised that I had to bake the base and cool it before the lime filling could be poured in. No baking beans needed for this inital bake unlike the Tarte au Citron.
The grating and juicing of the limes was intense and made me crave a mojito. Once it was all grated I whisked it into the lashings of condensed milk and egg yolks, which I lovingly separated from their whites to save for the magnificent meringue.
Then to pour the limey goodness onto the biscuit base which was now a thick greenish creamy paste and bake it in the oven. The lack of light in my oven could pose a problem for checking the bake, but I’ve lived with it for over 2 years now and found a torch is a handy cooking tool.
Now for the exciting bit. I’ve never made Italian style meringue before. (and only made normal meringue for the first time recently!) I saw it on the Great British Bake Off being created very precisely with thermometers and such like. If you’ve read any of my blog you will know by now that I simply don’t do precise, so I was relieved that a thermometer was not needed in this recipe. The only thermometer I own is a forehead strip one that I bought during the Swine Flu Panic last year. Somehow I don’t think I could use that to measure the temperature of sugar syrup…
8 egg whites were whisked into a frothy frenzy whilst the sugar and water bubbled merrily on the stove. I couldn’t remember if you were supposed to stir sugar constantly or if it makes it return to it’s crystallised state, so I did a bit of both. Stir, let it bubble, stir again. It eventually reached what I assumed to be the ‘soft ball stage‘. A mystical sugary state that frankly I’ve never heard of before I attempted to make fudge the other week, which was a disaster, so I clearly can’t recognise this stage of sugary wonderment. To be on the safe side I let it bubble some more..
When the sugar is syrupy and hot enough it needs to be poured slowly into the egg whites whilst whisking it. It’s a good job I can multi task, as I poured the liquid molten lava with one hand and held the electric whisk with the other, praying I wouldn’t slip and scald myself. When I win the lottery I have promised myself a Kitchen Aid mixer (and a bigger kitchen).
I think I may need a bigger bowl if I’m ever going to make this again. It was amazing. Compared to uncooked meringue this was like magic. It quadrupled in size and almost over flowed the bowl! The only downside was after all the sugar was incorporated was that it involved 15 – 20 minutes of more whisking. Thank god for my little electric whisk and my ipod on random. Elvis and whisking. What can be better?
Once the meringue had cooled, it was cooked through and ready to be assembled on top of the lime pies. It was a sticky process. With each mountain of meringue in position I popped them all in the oven for the final bake!
What a wonderful sight! So impressive! I struggled to get the pie into my cake box to transport to work. So cling wrapped it to the hilt and carried it like a baby. I got A LOT of smiles from strangers on my way to work that morning! Someone actually offered me their seat on the metro. It just goes to show people LOVE cake and Key Lime Pie is an attractive bake.
This pie goes a long way. We shared it amongst 11 people and then I still had 3 mini pies at home! (don’t worry I didn’t eat them all by myself) The wonderfully sweet meringue balanced out the sharp and creamy lime. The digestive base tasted almost gingery after their third bake in the oven. Perhaps it was the addition of rich tea biscuits, whatever it was, it was wonderful.
