Lavender-Poached Peaches & Blackberries

Combine water, orange juice, honey, large lavender sprigs and vanilla bean in a large nonreactive saucepan (see Tips). Bring just to a boil, stirring until the honey dissolves. Add whole peaches to the boiling liquid and cook, gently turning, until the skins start to loosen, 1 to 2 minutes. Remove the peaches to a colander with a slotted spoon; rinse under cold water and let drain.

Meanwhile, adjust the heat so the poaching liquid boils briskly and begins to reduce. Using a paring knife, peel the peaches and add the skins to the boiling liquid. Cut the peaches in half vertically, keeping the halves intact. Remove the pits, if possible; if it's too difficult, leave them in until after poaching.

Adjust the heat to a bare simmer. Return the peaches to the pan and poach until they are not quite tender when pierced with a fork, 3 to 7 minutes; they should still hold their shape. Transfer them to a nonreactive bowl with a slotted spoon. When cool enough to handle, gently cut out and discard any remaining pits. Cover and refrigerate for at least 30 minutes and up to 3 days.

Add blackberries to the barely simmering liquid in the pan. Poach for 1 to 2 minutes. Remove them to a small bowl with a slotted spoon. Cover and refrigerate for at least 30 minutes and up to 3 days.

Adjust the heat so the poaching liquid boils briskly and cook until reduced to about 2/3 cup, 14 to 18 minutes, watching carefully to prevent scorching. Strain the liquid through a fine sieve into a nonreactive bowl, pressing down on the solids to force through as much liquid as possible; discard solids. Cover and refrigerate the syrup for at least 30 minutes and up to 3 days.

To serve, let the fruit and syrup come to almost room temperature. Arrange the peach halves in pairs in individual serving bowls. Spoon a small scoop of frozen yogurt or ice cream into each half, if desired. Top with the blackberries and drizzle with the fruit syrup. Garnish with small lavender sprigs or flowers, if desired.
