Notes
Cracking is normal and expected for this flourless sponge — don't worry about it.
Cover the cooling sponge with a damp tea towel to help reduce excessive cracking.
Whip the cream to soft peaks only, for the easiest spreading.
Ensure the sponge is fully cool before filling and rolling.
Freezes well, whole or in slices, for up to 2 months.
