LowCarb Asparagus Dinner Soup
Trim off ends of asparagus and remove about 4" of the skin of each stalk, keeping the ends and peels. Cut asparagus into 1" pieces.
1) In a pan mix the asparagus peels and trimmings with the chicken stock bringing to a boil.
2) Remove from heat and let stand for 15 minutes. Strain stock and reserve.
3) In a pot of salted boiling water blanch the asparagus tips for 2 minutes.
4) In a large pot melt the butter over a low heat and cook the leeks, onion and celery, seasoning with salt and pepper, for 6 minutes. Add the 1" asparagus pieces and mix.
5) Add the infused stock and water, bring to a boil and simmer, for 10 minutes until asparagus is tender.
6) Puree the soup in a blender until smooth. Return pureed soup to large pot and leave to cool.
7) In a heatproof bowl whisk eggs and 1/4 cup lemon juice together, adding 1 cup of the lukewarm soup at a time, while whisking constantly.
8) Whisk the egg mixture into the remaining soup.
Cook the soup over a low heat without boiling. Once soup is hot, add remaining lemon juice and salt and pepper.
