1 cup white sugar
1 cup fresh lemon juice (about 4-5 lemons)
zest of 3 lemons
1/2 cup unsalted butter, melted
1. In a large microwave-safe bowl, whisk together the sugar and eggs until smooth and thoroughly combined. Whisk in lemon juice, lemon zest and butter.
2. Cook in the microwave on full power for one minute intervals, stirring after each minute. This process will take about 3-5 minutes depending on the strength of your microwave. You will know the lemon curd is done cooking when it coats the back of a metal spoon.
3. Remove from the microwave, push through a fine, mesh sieve and pour into sterile jar.
I used bottled lemon juice to make this, and skipped the zest. It still turned out really well.
