Instructions
- Step 1: Preheat oven to 375°F. Butter six 6-ounce ramekins generously with unsalted butter and dust each with 2 tbsp granulated sugar, tapping out excess.
- Step 2: Melt 4 oz chopped bittersweet chocolate with 2 tbsp unsalted butter in a heatproof bowl over simmering water, stirring until smooth. Remove from heat and stir in 1 tsp vanilla extract and 1 tsp finely grated orange zest.
- Step 3: In a large clean bowl, beat 4 large egg whites with 1/4 tsp cream of tartar until soft peaks form. Gradually add 1/4 cup granulated sugar and continue beating until stiff, glossy peaks form.
- Step 4: Stir the 4 large egg yolks into the cooled chocolate mixture until combined.
- Step 5: Gently fold one-third of the egg whites into the chocolate mixture to lighten it, then carefully fold in the remaining egg whites until no white streaks remain, preserving as much air as possible.
- Step 6: Divide batter evenly among prepared ramekins, filling them almost to the top to encourage a high rise.
- Step 7: Bake for 12-15 minutes or until soufflés have risen high and the tops are set but slightly wobbly in the center.
- Step 8: Remove from oven, dust tops with powdered sugar, and serve immediately to enjoy the impressive height and delicate texture.
