Source: Nigella Lawson’s How to Be a Domestic Goddess Notes: As noted above, the dough for these Danishes should rest in the fridge overnight. I have included notes below if you need to rush the process along — the Danishes can be made start to finish in as few as 6 hours. The filling amount listed below is for 6-8 pastries. Double it if you are making the full amount of pastries. Day-old pastries reheat quite nicely at 350F for 10 minutes or so.
