Sauce for Plum Pudding (Superior)

The sauce can be made up to 2 days ahead. Store in an airtight container in the refrigerator. To serve, reheat very gently in a double boiler or heatproof bowl set over simmering water, stirring constantly. Do not microwave or apply direct heat, as this will break the emulsion. Whisk in 1-2 tablespoons of warm cream if needed to restore consistency.

Store in an airtight container in the refrigerator for up to 5 days. The sauce will thicken considerably when chilled. Reheat gently using a double boiler method over barely simmering water, stirring constantly until warmed through and smooth. If the sauce appears separated, whisk vigorously off heat or pulse briefly with an immersion blender to re-emulsify.
