In a wide-mouth jar for which you have a lid (or a bowl), combine the lemon juice, vinegar, tahini, Dijon mustard, garlic, maple syrup, salt, and pepper to taste. Whisk well to combine.
Now stream in the olive oil, whisking as you go, until emulsified. NOTE: If it feels too thick, whisk in cold water, one tablespoon at a time.
Taste, adding more salt as desired. For more acidity, add more lemon juice or vinegar. For sweetness or balance, add more maple syrup.
Store in a sealed jar in the fridge for 7 to 10 days. It will thicken, so stream in some cold water, whisk, and continue you reach your desired consistency.
