# How-To:
01 - Preheat oven to 325°F. Butter a 2-quart baking dish and set aside.
02 - Place butter and chopped semisweet chocolate in a heatproof bowl over simmering water; stir until smooth. Remove from heat and allow to cool slightly.
03 - Using a stand mixer fitted with paddle attachment, beat eggs and sugar on medium-high speed for 5 to 10 minutes until thick, pale, and ribbon-like.
