Combine all of the ingredients in a large microwave-safe bowl. To avoid bubble-overs, the contents should fill no more than 1/4 of the bowl; an 8-cup measure works well here., Microwave the ingredients in 1-minute increments, removing from the oven and stirring to combine after each minute., When curd starts to thicken; coats the back of a spoon; and starts to mound a bit as you stir, it's done. This will take anywhere from 4 to 10 minutes, depending on the strength/power of your microwave. The curd's temperature should have reached at least 185°F., Stir the curd one more time. If you see any small bits of cooked egg white, pass the curd through a fine-mesh strainer to remove them., Spoon the curd into a storage container, and refrigerate until firm., Keep curd refrigerated for up to 3 weeks; freeze for longer storage.
