- Fridge: The mousse will keep well for up to 3 days when stored covered in the fridge.
- Freezer: Not ideal. The texture can change upon thawing due to the fat content in white chocolate and cream.

Troubleshooting Tips
If something didn’t go quite as planned, don’t worry. Here’s how to fix (or prevent) common issues:
- Mousse is too runny?
Likely the cream wasn’t whipped enough or the chocolate was too hot when mixing. Next time, cool the chocolate more and ensure soft peaks in your cream. - Chocolate seized or turned grainy?
White chocolate is sensitive. Always melt it slowly over gentle heat. Avoid any water getting into the bowl—it causes chocolate to seize. - Mousse is grainy?
This could happen if the cream or whites are over-whipped, or if folding was too vigorous. Always be gentle during mixing.
Scaling the Recipe
Need more (or less) mousse?
The recipe scales up beautifully. Just maintain these ratios:
- For every 4 oz of white chocolate, use 1 cup heavy cream.
- Optional: 1 egg white per 4 oz of chocolate.
So for a double batch (8 servings), you’d use:
- 16 oz white chocolate
- 4 cups cream
- 2 tablespoons vanilla
- 4 egg whites (optional)
