When it is cool, cut it into squares. Dust it with more confectioners sugar, if desired.
Mom's Cooking Club Lesson: How to store lemons? I've always stored my lemons in the refrigerator because they last longer. But the last batch I bought, I put in my fruit bowl. I got much more juice when they were at room temperature. Unfortunately, they don't stay as fresh as those stored in the refrigerator. So, my conclusion.....if you're going to use up your lemons in a week or so, keep them out in a bowl (it's pretty that way too) but if you want to keep them fresh longer, then put them in the refrigerator.
