A Korean Pear is like the love child of a big green apple and a Bosc pear â round, bigger than typical pears, with a crisp, sweet, white interior with a brownish-yellow skin. Itâs hard and crisp when ripe, not like other pears that must soften to be ripe. Itâs no wonder these are sometimes referred to as apple pears. The beauty of Korean pears is they are superbly crisp, juicy and sweet with the thinnest skin (no need for peeling). Theyâre good in any salad where you might use chopped apples, or simply sliced and eaten for a snack or dessert.
