Method
- Preheat your oven to 325°F (165°C) and line an 8x8 inch square baking pan with parchment paper, leaving an overhang for easy removal.
- Make the strawberry reduction: In a small saucepan over medium heat, combine diced strawberries, 1 teaspoon sugar, and lemon juice. Simmer and stir until juices release and thicken into a jam-like consistency. Set aside to cool.
- Melt the foundation: Place the butter and chopped white chocolate in a heat-proof bowl over a pot of simmering water. Stir constantly until the mixture is glossy and smooth. Remove from heat and let cool slightly.
- Create the crackle top: In a separate large bowl, whisk the eggs and 1 cup of sugar vigorously for 3 to 5 minutes until the mixture reaches the 'ribbon stage' (pale, thick, and falls in slow ribbons).
- Incorporate fats: Gently fold the cooled white chocolate and butter mixture into the egg mixture using a spatula, being careful not to deflate the air. Stir in the vanilla bean paste and lemon zest.
- Add dry ingredients: Sift the flour and sea salt directly over the wet ingredients. Fold gently until just a few streaks of flour remain; do not over-mix.
- The swirl: Pour the batter into the prepared pan. Drop small spoonfuls of the strawberry reduction over the top and use a toothpick to swirl the fruit into the batter.
- Bake: Bake for 30-35 minutes until the edges are set and a toothpick comes out with a few moist crumbs attached. The center should still look slightly soft.
- Cool: Let the brownies cool completely in the pan for at least 2 hours. This is essential for the fudgy texture to set properly.
Notes
For a deeper flavor, you can brown the butter before adding the white chocolate. If fresh strawberries aren't available, frozen berries can be used but require a longer simmer time to remove excess moisture. Store in an airtight container for up to 3 days. Avoid using white chocolate chips with stabilizers, as they won't melt into the correct fudgy base.
