Here is the recipe for my ho-made (hee hee...that's for you RCH) lemon curd that came out so amazingly tasty that I kept sneaking tastes of it and finally had to hide it from myself in the back of the fridge.
You can use it for a lemon meringue pie, spoon it over ice cream or cake, fill cupcakes with it, pour it into tiny tart shells, pair it with berries and cream. So many possibilities. And if you don't like lemon you can switch it up with lime, orange or even grapefruit.
The recipe is a bit intense, and you're going to need a bit of prep to make it, but it's SO worth it.
Master Lemon Curd
adapted from Secrets of Baking by Sherry Yard
2/3 c. sugar
2 T. finely chopped, grated or rasped lemon zest
3 large eggs
4 large egg yolks
1/2 c. fresh lemon juice
1/4 c. fresh lime juice
(you can also use all lemon juice...3/4 cup. Using part lime adds an extra citrus dimension.)
6 T. unsalted butter, cut into half inch cubes and chilled
-Combine the sugar and lemon zest in a food processor and pulse for about 1 minute, until the sugar is yellow and fragrant. Alternately, use a mortar and pestle or a small bowl and a fork. Clean and dry your food processor (if using) for later in the recipe.
-Fill a medium saucepan three-quarters full of water and bring to a simmer over medium heat.
-Combine the lemon sugar, eggs and egg yolks in a medium heatproof bowl and whisk for 30 seconds.
-Place the bowl over the simmering water and whisk continuously for 15 seconds or until the sugar is completely dissolved- to check for this, stick your finger in, if you feel granules, the sugar isn't dissolved~keep whisking until it is.
-Once the sugar is dissolved, add the lemon and lime juice. Whisk continuously for about 5 minutes, scrape down sides of bowl a couple of times with a rubber spatula.
-Insert a candy thermometer and keep whisking ~ the curd is done when it has a temperature of 160*F, and a consistency similar to sour cream. Go by temperature, not time. (Mine took about 10 minutes to reach it...time will vary wildly.)
-Transfer the curd into your food processor and pulse while you add the butter one piece at a time. Alternately, transfer the curd to a clean large bowl, and whisk the butter in by hand one piece at a time. (Yeah! More whisking!!) Once all the butter has been added, pulse or whisk for an additional 10 seconds. You're looking for a homogeneous texture.
-Strain the curd through a fine mesh strainer into a clean glass bowl. Cover it with plastic wrap, pressing the plastic directly onto the surface of the curd to prevent a skin from forming. Stir the curd occasionally until it has cooled completely.
-At this point you can use it or store it in an airtight container in the fridge for a couple weeks. You can also freeze it for several months without quality changes when thawed. Put it in the fridge and let it come up to temp for 24 hours before using.
Makes about 2 cups
* I made a few changes to recipe from it's original form, and I'm posting the differences here so you know what and why.
The original recipe calls for an ice bath, which is really just a bowl of ice cubes that you can sit the heatproof bowl in to help cool down the curd when you're finished whisking. I noticed (as did several other people who have made it) that this step wasn't really necessary. Especially if you are whisking it by hand. The chilled butter and the whisking seemed to bring the temperature down considerably, so by the time I put it in the ice bath it was just barely warm. However, you can keep this step if you need to cool it down in a hurry or if you are a big fan of ice baths. :)
Also, this curd is just on the edge of quite tart, so if you would like the curd a little sweeter I would suggest upping the sugar to 3/4 cup.
You can also whisk in an extra 2 tablespoons of cubed and chilled butter if you'd like richer curd. I upped it from the original 4 tablespoons to 6, but felt like 6 was plenty...plus all that whisking! For cubing, take your butter out of the package, put it on a piece of waxed paper, cut into cubes, wrap it up in the waxed paper and put it back in the fridge until you're ready to use it in the recipe.
