Soak the grape leaves in a bowl with cold water to cover for 30 minutes, changing the water 2 or 3 times.
Cook the barley, drain it, and cool it, but do not rinse. You want the barley to be a little sticky.
Combine the barley, onion, garlic, mint, lemon juice, olive oil and pine nuts (if using), salt, and pepper in a mixing bowl and mix well. Correct the seasoning, adding salt or lemon juice to taste: the mixture should be highly seasoned.
Rinse the grape leaves in a colander. Blanch the leaves, a few at a time, in a shallow pan of boiling water for 1 minute. Drain the grape leaves in a colander, rinse with cold water, and let cool. Blot dry.
Lay a grape leaf on your work surface, stem end toward you. place a heaping tablespoon of filling in a row along the bottom third of the leaf. Roll up the leaf to form a tight cylinder, folding in the side flaps halfway up, as you would to form an egg roll or a blintz. The idea is to form a compact roll about 3 inches / 7.5 centimeter long and 1 inch / 2.5 centimeter thick. Assemble the remaining grape leaves the same way. The grape leaves can be assembled several hours ahead and stored, covered, in the refrigerator.
Place the stuffed grape leaves in a nonreactive baking dish with 1/2 inch / 1.3 centimeter vegetable stock or water. Cover the pan with foil. Bake the grape leaves for 30 minutes, or until tender. Drain off any extra cooking liquid before serving. Serve either hot or cold with dipping sauces below.

Heat the olive oil in a large heavy saucepan. Add the onion and garlic and cook over medium-low heat until just beginning to brown, about 5 minutes. Remove the pan from the heat.
