Part 3/7:
To kick off the mousse-making process, start by setting up a double boiler to gently melt the chocolate. In a metal bowl over simmering water, whisk together egg yolks, granulated sugar, and a generous splash of O'Driscolls Irish whiskey. Constant whisking is crucial here – it ensures the egg yolks cook evenly without scrambling.
Once this mixture thickens, pour it over the chopped bittersweet chocolate and let it melt into a velvety blend. Following the melting stage, strain the mixture through a sieve to achieve a silky-smooth consistency, an essential factor for any mousse recipe.
