Absolutely Nothing To Cook : The Key To Key Lime Pie, by Micki MyersPosted: August 31, 2012
One of the most glorious food items that gets utterly ruined when people try to mass market it is Key Lime Pie. One of the biggest food faux pas is when people mistake or knowingly substitute your regular green limes for key limes, which are not the same thing at all. The key lime is a tiny thing, the size of a cherry, and looks like a yellowish-mottled kumquat. Its flavor is far less tart than its Hulkier cousin, too — instead it is sweet yet piquant, with none of the bitterness of a lemon. The pie made from it is designed especially to showcase this lovely citrus flavor, and is well worth making.
First, you’ll need to zest and squeeze 20 or so key limes. Use a plane zester and an old-fashioned glass squeezer upon which you can palm each half lime. I find myself giving it a quick press and then pinching the spent skin over the glass knob to finish it off. I also take my time, alternating with other chores; try to do them all at once and you’ll bugger up your wrist something chronic.
Make a graham cracker or biscuit crumb base. If you’re American this means zapping graham crackers in a food processor (or just buying it already crumbed); if you’re British it means doing the same with Digestive Biscuits. Mix with the melted butter and sugar, press into a tin, and bake for 5 minutes or so until it’s firmed up a bit.
Mix the zest in a bowl with the egg yolks and lime juice, then add the condensed milk. A tin of condensed milk out to be a pantry staple for emergencies. Be sure to use a spoon to scrape every last succulent, sugary drop of it from the tin rather than simply diving after it with your tongue.
You’ll have a luscious, pale custard. Pour this into the biscuit base, set the whole thing onto a baking sheet, and pop in the oven for 15 minutes until the heat has had a chance to work its magic on the eggs. It will still seem a bit too wobbly when you take it out, but that’s OK — the next step firms it up. Once it has cooled to room temperature, put some cling film over it and pop in the fridge for a couple of hours.
The finished pie will be diminutive in height, and a luxurious creamy color flecked with bits of pale green zest. Cut small slices; this baby’s rich.
If there’s any left, refrigerate until midnight, then sneak out of bed and polish it off.
