I have made this soup a dozen times or more. My learnings:
Use a good brand of buttermilk. The cheap store brands don't taste very good. The buttermilk doesn't need to be full fat, 1% will do. The freshest corn and basil will make a difference. I don't add ice cubes because I like the soup a little thicker. I do strain the soup to smooth it out. Finally, I make this soup hours if not a day ahead of time and chill it. It is a wonderful starter for summer dinner parties.
We love this! Easy and refreshing summer starter.
Changes:
Make a few hours (or even a day) ahead and chill -- improves soup greatly.
NO ice cubes -- too watery.
DO NOT strain -- too watery.
If your basil is strong, reduce amount or flavor will overwhelm the soup.
In a pinch, substitute 3 cups frozen corn for the fresh ears -- the soup is still delicious.
Don’t discard the cobs. If you can’t bear doing this now freeze them and do it when it’s cooler but make a stock out of them...it makes the best stock to use in all sorts of ways. #zerowaste
Straining the soup in a mesh nut milk bag is far less tedious than using a fine-mesh sieve!
I have to disagree that straining made the soup "watery." It is a thin soup, but silky and flavorful. I sampled it before straining and it was gritty and raw tasting. Straining the soup made for a refined taste experience. Skipped the ice cubes as suggested, as adding water would tend to make a dish watery...
This recipe was a hit despite my using frozen corn. I googled tastiest frozen corn and picked one I had access to (Kroger’s). I made two batches, one nondairy with coconut milk and the other dairy with 1 cup Greek yogurt plus 1/2 a cup milk. My dairy free guest and coconut-loving husband both enjoyed the coconut version but the dairy version really sang and is what makes me want to cook the recipe again. I’ll repeat when I’m visiting my folks during corn season, but frozen corn works great!
