Lemon Curd is a great companion to Irish Soda Farls that we make each St. Patrick’s Day. Curd is essential a fruit custard made with egg yolks. This recipe calls for a double boiler. I don’t know about you, I don’t know anyone who owns an actual double boiler. It isn’t even necessary as long as you have a sauce pot and metal bowl that fit together nicely. You’ll notice in the picture below the recipe my very dirty stove. You will also notice how the “double boiler” should look. You do not want the bottom of the bowl to touch the water. Essentially, the point of a double boiler is to heat something using indirect heat, to avoid it scorching or curdling. It’s used to melt chocolate and make custards, among other things. The custard is heated by the steam created by the boiling water underneath.
This lemon curd recipe results in a creamy curd, not the gelatinous kind many use for a lemon meringue pie. It’s perfect for a topping for breads or as a spread.
CREAMY LEMON CURD
5 eggs yolks
1 cup sugar
1/2 cup fresh squeezed lemon juice
1 TBS lemon zest
4 TBS butter, cut into pats and chilled
Fill a small pot with about an inch of water, place on the stove over medium-high heat. Meanwhile, in a metal bowl that fits on top of your pot, whisk together the egg yolks and sugar. Whisk well, until light and creamy. For smooth curd, pour the juice through a fine mesh strainer to remove any pulp. Whisk in the lemon juice and zest. When the water comes to a boil, quickly reduce heat to low, to keep to a simmer. Place bowl on pot and whisk continually until thick. This takes about 10 minutes, but will vary. You know it’s ready when it thickly coats the back of a spoon or reached 160 degrees on a candy thermometer. Remove from heat and add in the butter, one pat at a time, stirring each until it melts before adding the next pat. Pour into a container or bowl and press plastic wrap against the surface of the curd. Refrigerate until cool.
