Crispy Meringue Bark with Purple Sweet Potato Swirl

Crispy Meringue Bark with Purple Sweet Potato Swirl
🛒 Ingredients
4 large egg whites (room temperature)
1 cup (200 g) granulated sugar
1/2 tsp cream of tartar (or a few drops of lemon juice)
1 tsp vanilla extract
1/2 cup purple sweet potato purée (smooth and thick)
Pinch of salt
🍠 Make the Purple Sweet Potato Purée
Peel and cube 1 medium purple sweet potato.
Boil or steam until very soft (about 15–20 minutes).
Mash or blend until completely smooth.
Let it cool completely before using.
🍳 Instructions

1. Preheat
   Preheat oven to 110°C (230°F)
   Line a baking tray with parchment paper.
2. Make the Meringue
   In a clean bowl, beat egg whites with a pinch of salt until foamy.
   Add cream of tartar.
   Gradually add sugar (1 tablespoon at a time), beating continuously.
   Beat until stiff, glossy peaks form.
   Mix in vanilla extract.
3. Add the Purple Swirl
   Gently fold in spoonfuls of the purple sweet potato purée.
   Don’t fully mix—leave streaks for a marbled effect.
4. Shape the Bark
   Spread the mixture onto the baking sheet (about 1–2 cm thick).
   Use a spatula to create swirls and texture.
5. Bake Low & Slow
   Bake for 1.5 to 2 hours, until dry and crisp.
   Turn off oven and let it cool inside (door slightly open).
6. Break & Serve
   Once completely cool, break into rustic bark pieces.
   ✨ Tips
   Make sure your bowl is grease-free or the meringue won’t whip properly.
   For extra flavor, sprinkle crushed pistachios or coconut flakes before baking.
   Store in an airtight container (humidity will soften it).
   🍽️ What It’s Like
   Light, airy, crispy, and slightly chewy inside—with a subtle earthy sweetness from the purple sweet potato and a naturally stunning violet swirl.
