But after having tasted the soup, I am not sure if I should call it Mexican soup or Thai soup?!? And this is made out of only 4 ingredients!
I have a lot of homemade tomatillo salsa in my fridge. I make it by roasting tomatillos, garlic cloves, onions, and jalapenos in 425F oven until they are somewhat charred, about 20 minutes. Then I blend the whole thing in my Vitamix (blender) with some chopped cilantro. Add some salt, and your salsa is done. You can use this to make green chili verde, or as a condiment for tacos.
I want to turn some of the salsa into soup. To give body to the soup, I need to add some nuts and cream. Pistachio nuts would be great but I don't think I have any! I saw a bag of Thai Lime Chili Cashews from Trader Joe's. Um... that might work! So I combine 1 cup tomatillo salsa (feel free to use a store-bought one, normally called (Mexican) salsa verde) with 1 can of low salt chicken broth or vegetable broth if you want it to be vegetarian (I use Swanson's which won a taste test in Cook's Illustrated, that's good enough for me), and 1 cup of cashews in my Vitamix. Blend until the mixture is smooth.
Pour the mixture into a medium saucepan over medium high heat to boil. Taste for seasoning. I only have to add some salt and a dash of maple syrup to balance the flavor. Now reduce the heat and add in about 1/2 cup of cream. Heat the soup up, but do not boil vigorously. Adjust seasoning again. Delicious, right?
To my surprise, it tastes more like Thai tom kha soup. I am thrilled to have made this discovery. That's why cooking is fun for me. I learn something new every day. I certainly will make tomatillo salsa so I can make this soup again. It is very rich and flavorful, perfect in a little shot glass on your holiday buffet table. It will wake up your guests' palate with a little kick! But I am not sure about the name....
May be I should call it Tom Kha Tomatillo Soup! We can put it up for a vote. :)
