This was very delicious, refreshing and elegant. I skipped the toast but crumbled the feta, with the corn kernels, into the soup. Perfect. I kept pretty much to the recipe, otherwise. No single flavor stood out, which I think is how it should be. More vinegar or lots of lemon or more anchovy or whatever might threaten the delicate balance of this one. I rarely say that, but there's perfection here...
I have made this soup with and without the anchovies. i have found the soup has much more depth with the anchovies added...so I wouldn't leave them out.
This is an excellent warm weather lunch and sooo easy!
This turned out to make a really complex spring soup, with a few spontaneous changes. First, I used a VitaMix to get a really smooth puree. Use twisty armenian cukes; 1 T of fish sauce, instead of anchovies; green garlic, instead of the garlic and scallions; lots of mint and lemon balm, by way of herbs; 5 or 6 whole kumquats and about 1 T lemon juice, instead of vinegar; puree the avocado with the soup; add salt and hot sauce at the end to taste. Garnish with chopped mint or basil and EVOO.
So good! Used a bit of a poblano from the garden to keep the spice down. My 11-month old grand-daughter loved it as much as we did!
A delicious easy soup to make. Made it twice in two weeks because of all the cucumbers in my garden. I added a lot of fresh tarragon and a little fresh basil which I also had in the garden, and did the yogurt and water mix. I loved the tarragon flavor! Topped the soup with a drizzle of olive oil and a little ground pepper and crumbled feta and it was divine!
Can you make this soup with Greek yogurt?
