Bosc pears have a more firm, dense flesh than other pear varieties, so they are ideal for use in baking, broiling or poaching. They retain their shape and texture better than other varieties, and their flavor is less likely to be overwhelmed by the use of strong spices like cinnamon, clove or nutmeg. Of course, they are also excellent for fresh eating, particularly by those who prefer a firm texture.
Bosc pears are sweeter and more flavorful earlier in the ripening process than other pear varieties. As a result, the complex flavor, honey-sweetness, and juiciness of Bosc can be enjoyed before their flesh has fully softened.
Since the flesh density of Bosc is greater than other pears, it's important to take this into consideration when determining when Bosc pears are ripe. The Check the Neck™ test, where gentle thumb pressure is applied near the stem end, is still the best method for checking Bosc for ripeness. However, keep in mind that Bosc will "give" less than other pears when they are ready. Sometimes, Bosc will also show a slight wrinkling at the base of the stem as well as a minimal color change as they ripen-- a green hue under the russeted skin will turn more yellow. However, color change is not as reliable as Checking the Neck™.
Ripen Bosc pears as you would any other variety: leave them at room temperature and only refrigerate after the pears have ripened.
