Step 7: Serve
You want to make sure everyone is eating the soup as soon as possible after you've declared it properly seasoned, as these veggies aren't getting any fresher. There's a tangy, vibrant taste to just-mixed-in fresh herbs that isn't the same after a longer simmer.
That said, this also makes excellent leftovers. It stores and microwaves well, and the flavors will mingle in interesting ways after a night in the fridge. You may want to reserve some additional fresh herbs to sprinkle over the top, or maybe squeeze a slice of lemon if you prefer that super-fresh taste, but otherwise it's only going to get better with time.
