Can I refrigerate homemade puff pastry made ahead of time?
Classic puff pastry absolutely needs a final resting and cooling time in the fridge before you use it for your croissants, palmiers, danishes....

Most recipes give a minimum rest of 30-60 minutes after the last "fold", but overnight in the fridge is absolutely fine. I'm not sure whether storing it for two days might have negative side effects, but up to one day is no problem at all.
