Heat de oven to 200 gr Celsius. Grease 4 little spring forms or Baking dishes (diameter 12 cm) with some butter and put in every Spring form one slice of puff pastry.
Put the Puff pastry pies into the oven and bake them in 10-12 minutes.
For the sauce: Melt 125 gr. of butter over a low heat and set aside.
Mix in a bowl (glass or stainless steel) 2 egg yolks. With 2 table spoons of water. Heat the mix slowly au baine marie (above a cooking pot with hot water) and mix with a guard around 4 minutes until you have a frothy and creamy sauce.
Get the bowl of the aubain marie cooking pot and put slowly the melted butter into the mix. Keep mixxing until all the butter is mixes with the egg yolk sauce.
Add lime juice, pepper and salt to your own taste.
If you don’t have time to make the Hollandaise sauce, then you can also use an (almost) ready made kind of sauce. The Hollandaise sauce from Knorr tastes great with this pie.
At the same time cook the 200 gr. of fresh green asparagus tips in around 2 minutes and set them aside with the cover on the cooking pot.
Get the puff pastry pies out of the oven and out of the spring forms. Put them on some plates.
Melt some butter and bake the 4 (quail) eggs. Quail eggs aren’t available in every time of the year. So you can also use normal eggs. Try to use the smallest eggs you can find, bake them and after baking you cut of some of the white part of the egg. You can easily fit the egg on the small pies then.
Divide the asparagus tips over the pies, put some Holllandaise sauce over it and decorate with a baked egg.
Enjoy your starter!
