Preheat the oven to 200 °F degrees. Line a large baking sheet with parchment paper and set aside.
In the bowl of a completely clean stand mixer fitted with the whisk attachment, whip the egg whites on medium speed for one minute to froth it up and build some body. Then, whip on medium-high speed for 8 to 10 minutes total – once soft peaks begin to form, start adding the lemon juice, and the sugar one teaspoon at a time. You should have stiff, glossy peaks. A stiff meringue = a happy pavlova.
Using a rubber spatula, pile the majority of the meringue onto the center of the parchment paper covered baking sheet. Using an offset metal spatula, spread the meringue into a large dinner plate sized round.
Fill a piping bag fitted with an open star or round tip with the remaining meringue. Pipe meringue kisses surrounding (but not touching) the central meringue, or pipe another parchment-covered baking sheet with kisses.
Place in bottom rack of oven. Do not open the door to check on the meringue at any point! Bake for ninety minutes; when the baking time is up, turn the oven off and let the pavlova and meringues cool completely inside the oven without opening the door. You can even bake this in the evening and turn off oven before going to bed, leaving overnight.
