Question: how much juice in half a lemon?
Answer: 1 Large Lemon (6 oz.) If your recipe calls for 3 tablespoons of lemon juice, then you would need to buy at least one small lemon. Conversely, if your recipe calls for the juice of one lemon and all you have is bottled lemon juice, then you know you'll need between 3 and 5 tablespoons of juice.
