Ingredients
1/2 cup balsamic vinegar
1 cup sugar
5 to 6 fresh rosemary sprigs
1/8 teaspoon ground pepper
4 firm, ripe Bosc pears (about 2 pounds total), peeled and cored (see note, below), stems left intact
Vanilla ice cream, for serving (optional)
Preparation
In a saucepan just large enough to hold pears on their sides, combine 5 cups water, vinegar, sugar, rosemary, and pepper. Bring to a boil, stirring until sugar has dissolved. Remove from heat.
Arrange pears on their sides in a single layer in poaching liquid. Cover and simmer, turning occasionally, until tender, 25 to 30 minutes. Using a slotted spoon, carefully transfer pears to a plate. If making in advance, let pears cool; then cover and refrigerate up to 3 days.
Bring poaching liquid to a boil; cook until slightly syrupy, deep brown in color, and reduced to 3/4 cup, 35 to 40 minutes. Strain through a fine-mesh sieve (discard solids). If storing, transfer syrup to a covered container, and refrigerate up to 3 days. (Store pears and syrup separately.)
Serve pears chilled or at room temperature: Cut a thin slice from the bottom of each pear so it can stand upright. Place one on each of four serving plates along with vanilla ice cream, if desired. Drizzle with syrup.
