Best is to work during the night time when the temperature is cooling down. You have to be very fast... and you need space in the fridge to store the prepared ingredients. I think it's understandable that I'm not very keen on doing this.
But if you have the chance to get fresh strawberries and REAL whipping cream (you have to drive several miles to get this) it's a must to bake a strawberry-biscuit roll.
Bon appetit :)
