Briefly dip grape leaves in boiling water then rinse them with cold water and wipe dry. Sauté the onions with half the olive oil. After 4-5 minutes stir in the rice, 250mL hot water and the remaining ingredients, except for the oil and the lemon juice. Boil this mixture for 4 to 5 minutes.
Wrap one tablespoon of the mixture with a grape leaf and fold to make a little package. Repeat with the rest of the grape leaves.
Carefully place the dolmathes in a pot but don't overcrowd them. Add the rest of the oil and the lemon juice with 500mL of water and cover the pot with a lid. Boil at low heat for 30 minutes, until some water is absorbed and the rice is done.
