Shrimps and asparagus with dill and cream is quite unusual combination for me, but I must say it tastes delicious. I ate something similar when we lived in Austria and wanted to reproduce the recipe ever since.
It tastes especially good if asparagus is young and you manage to not overcook it to keep crunchy texture. Lemon juice helps to brings the best taste out of asparagus.
By the way, if you use frozen shrimps, thaw completely them before adding to salad.
