This summer berry pavlova has a crisp meringue shell with a marshmallow-soft center, piped rosettes around the rim, and a topping of whipped cream with blueberries, blackberries, and fresh cherries. A make-ahead gluten-free dessert that feeds a crowd.
Line a large sheet pan with parchment paper. Trace a 9-inch (23 cm) circle on the parchment, then flip it pencil-side down. Wipe the mixer bowl and whisk with vinegar or lemon juice on a paper towel to remove any trace of grease.
Add the egg whites to the bowl of a stand mixer. Beat on medium-high until foamy, then add the cream of tartar. Continue beating until you reach soft peaks.
Add the sugar 1 tablespoon at a time, giving each addition a few seconds to dissolve. After about a third of the sugar is in, add the rest in a slow, steady stream. This should take 8 to 10 minutes total.
Beat on high until the meringue is thick, glossy, and holds stiff peaks. Rub a little between your fingers. If it feels gritty, keep beating until smooth.
Sift the cornstarch over the meringue, add the vanilla, and fold gently with a spatula until fully incorporated.
Spoon a little over half the meringue onto the parchment and spread it into a nest inside your traced circle, smoothing the center so it stays low.
Transfer the remaining meringue to a piping bag fitted with a star tip. Pipe rosettes all the way around the nest, keeping them the same size and making sure each one touches the next.
Preheat the oven to 300°F (150°C). Place the pavlova in the oven and immediately reduce the temperature to 250°F (120°C). Bake for 1½ to 2 hours, without opening the oven door.
The pavlova is done when the shell is dry, pale, and lifts cleanly from the parchment. Turn the oven off, prop the door open a few inches, and let it cool in the oven for at least 3 hours or overnight.
Beat the cold heavy cream with the powdered sugar and vanilla to soft peaks.
Pit and halve the cherries. Rinse the blueberries and blackberries and pat them completely dry.
Just before serving, spoon the whipped cream into the well of the nest and pile the fruit on top. Serve right away.
Notes
Your bowl and whisk must be spotless and grease-free. I wipe mine with a paper towel dampened with vinegar, then dry it. Any trace of fat or yolk, and the whites will not whip properly.
Room temperature whites whip better. Separate them cold, then let them sit out for 30 minutes.
Not one speck of yolk. Fat kills egg whites. Separate each egg into a small bowl first, then transfer — that way one broken yolk doesn't cost you the whole batch.
Add the sugar one tablespoon at a time. I know it feels slow. Rushing it leaves undissolved sugar, which is what causes those amber beads of syrup on a baked pavlova.
Test it: rub a bit of meringue between your fingers. Smooth means ready. Gritty means keep mixing.
Make the rosettes touch each other. Gaps are where cracks start.
Don't open the oven door while it bakes, and don't pull the pavlova out to cool. A sudden temperature change is the fastest way to a collapsed shell.
Cracks are normal. Every pavlova cracks a little, and cream and berries cover everything. Make extra cream — not for serving, for camouflage.
Humidity is the enemy. Meringue pulls moisture from the air. On a rainy or very humid day, your pavlova may stay tacky no matter what you do. Pick a dry day if you can choose.
Can I use liquid egg whites from a carton? I don't recommend it. Cartoned whites are pasteurized, and they often refuse to reach stiff peaks. Use whole eggs and save the yolks for lemon curd or ice cream.
What if I don't have cream of tartar? I use ½ teaspoon of cream of tartar for stability. Substitute with ½ teaspoon white vinegar or fresh lemon juice. Add either one at the same point in the recipe when you would add the cream of tartar; you do not need to use both.
Leftovers and storage
Unassembled meringue: keep it at room temperature in an airtight container for up to 3 days. Do not refrigerate it. The fridge is humid, and it will go soft and tacky.
Assembled pavlova: eat it the day you top it. Once you add the cream, the shell starts softening within a few hours.
Leftovers: cover loosely and refrigerate up to 2 days. The texture changes to something more like a soft meringue cake, which is still delicious, just different.
Freezing: I do not recommend it.
Cracks: If it cracks, cover it with cream and fruit and tell nobody. Every pavlova cracks a little. It is part of the charm.
