go back into waitrose and get some peeled quails eggs (in the chiller). Say for 24 of the croustades get 12 eggs and halve them. Also buy a couple of pots of Waitrose's ready made hollandaise sauce. Buy some baby leaf spinach, stick it in a colander, pour hot water over until it wilts, allow to cool and chop medium finely (but make sure you drain the spinach thoroughly. Then place all your croustade cases on a baking tray, heat the oven to "medium". Put a blob of chopped spinach in the bottom, then half a quails egg, and then a blob of the hollandaise sauce. Put the filled cases in the oven and allow them to heat through (until the hollandaise is bubbly) and then serve slightly cooled. this is a Mary Berry recipe and absolutely wonderful. Have done this several times for guests. And a doddle with all the ingredients ready made from Waitrose. But recommend the peeled quail's eggs - they are pain to peel yourself, let Waitrose do all the work! Oh, and you can do the spinach stage ahead of time, so that you can just assemble them and stick in the oven as your guests arrive. enjoy! Chox.
