With a lemony tart filling and a lightly toasted topping, lemon meringue pie is a delicious and beautiful dessert. There are a few steps to making a homemade lemon meringue pie, but it's easier to prepare than one may think with these two tips. First, take the eggs out of the fridge the night before to be completely at room temperature. Room temp eggs are key for the filling and meringue. Second, pre-measure the ingredients before starting the recipe. Once you've started, things move quickly. Having measured ingredients handy means you won't overheat the filling or over-beat the egg whites.
