In a large microwave safe bowl (I use a 1 quart pyrex measuring cup) whisk together the 3/4 cup sugar, 3 large egg yolks, and 1 large egg until well combined. Whisk in the 1/2 cup fresh squeezed lemon juice.
Microwave the bowl on high for one minute. Remove and whisk thoroughly.
Microwave the bowl for another minute on high, and remove and whisk again.
Microwave on high for a third minute, remove and stir well. The mixture should have reached 175F* and coat the back of your spoon. Check with an instant read thermometer.
Slowly stir in the 1/2 cup butter that has been cut in cubes, a few cubes at a time, allowing them to melt as you stir.
Push the curd through a fine mesh strainer into a clean bowl. Be sure to scrape off the curd that clings to the bottom of the strainer, you don't want to miss one drop!
Cool the curd at room temperature, then refrigerate until cold. The lemon curd will thicken as it chills.
Keeps in the fridge for up to a week, or freeze for up to 2 months.
Notes
*Eggs begin to thicken around 160°F (71°C) and fully set by 170–175°F (77–80°C) ~ that’s your sweet spot for smooth curd.
