Took shortcuts. Microwave spinach on high for 4 min (till tender). Put flour in liquidizer, add spinach & stock - wizz then transfer to pot Add water. Boil till thickened. Add milk  -  12 Aug 2009

Thanks for posting :-) I fell in LOVE with spinach ever since I was a toddler and can eat LOADS of it almost every day, xi...so (as usual with me) I make this soup using 1 kilo of frozen spinach!... 2-3 cups of water and 4-5 cloves of GARLIC instead of onions (it does make a huge difference)- and when it's all thickened I like to swap milk for buttermilk...or add milk and serve the soup with a dollop of a soured cream, mmm...  -  17 Feb 2014

I have made this recipe twice, and I love it. There are several things I did the second time around that made it better (all gathered from other reviewers) 1. I used about 1 lb of fresh spinach and blended the spinach mixture. 2. Used 2 cups milk & 1 cup heavy cream 3. Used fresh onion and garlic 4. Added a dash of Celery Salt, Cayanne Pepper, nutmeg, and thyme 5. Mixed in about 1/4 cup Parmasean Cheese. Most of these ideas came from other reviews. Combining them all together makes a really good soup (and not bland at all).  -  12 Jan 2006  (Review from Allrecipes US | Canada)
