Key Lime Pie
Fresh limes are a must for this perfect citrus pie. Key limes, often found only in specialty produce departments, are smaller and rounder than the more common Persian limes. They also are more yellow than green. You can substitute Persian limes, but we don't recommend using bottled lime juice for this recipe.
Recipe Summary test
You can substitute the more widely available Persian limes for Key limes but avoid the bottled juice. Instead of the usual meringue or whipped cream topping, I prefer sweetened crème fraîche and a last-minute squeeze of fresh lime.
