Standard lemons work well in this recipe, but Meyer lemons, which have a sweeter flavor, are a delicious substitute if you can find them in good condition. Often, you'll find lemons that are too soft, or dry and shriveled. Avoid these. What you want are plump, shiny-skinned fruits that are firm but not hard and seemingly heavy for their size, which is a good sign that they're full of juice.
