30 fresh sorrel leaves (about 4 by 2 inches), leaves halved lengthwise and center ribs and stems discarded
Special equipment: a 1 1/2-inch round cookie cutter (at least 1 inch deep); wooden picks
Directions
Preheat oven to 425°F.
Wrap beets in foil in 2 packages (3 per package) and roast in middle of oven until tender, 1 1/4 to 1 1/2 hours. When cool enough to handle, peel beets and cut off stems and root ends. Halve beets crosswise and arrange, cut sides down, on a work surface. Cut out a cylinder from each half with cookie cutter. Halve each cylinder lengthwise, then cut crosswise into generous 1/4-inch-thick slices.
Line a tray with plastic wrap and brush plastic wrap with some oil. Cut cheese logs crosswise into 1/4-inch-thick slices with an oiled knife, then halve slices. Arrange cheese slices in 1 layer on tray and brush with some oil, then top each with a slice of beet.
Arrange sorrel leaf halves, veined sides up, on work surface. Put a cheese and beet stack in middle of each leaf half, then wrap sorrel over stack and secure with a pick.
