Flat-leaf spinach, which baby spinach is a variety of, is the most popular type of spinach used in salads and is what you will find when looking for spinach for salads in the grocery store produce section. It has a mild sweet-and-bitter flavor when raw that pairs well with sweet salad ingredients such as fruit, nuts, and tangy cheeses like feta and goat cheese. This is not the same as savoy spinach, which is best eaten cooked.
