FAQ
Can I make this without espresso powder?
Yes, substitute with instant coffee or omit entirely for pure chocolate mousse. The espresso adds depth but isn't essential.
How long does the mousse keep in the refrigerator?
Properly covered, the mousse stays fresh for up to 2 days. The texture is best within 24 hours of making.
Can I freeze chocolate mousse for later?
Freezing isn't recommended as it will change the delicate texture. The mousse may become grainy when thawed.
