Homemade balsamic vinaigrette is a staple recipe in our house. We like vinegary dressings and use twice as much olive oil as vinegar. To make a less vinegary dressing, add more olive oil to taste. I like to add a little sweetener to the dressing. Maple syrup or honey is lovely, or add a little fruitiness with your favorite jam (strawberry jam is especially good). If you are using a thicker balsamic vinegar or one that is aged, it may already taste more sweet, so you may not need to add sweetener.
1/4 cup (60ml) balsamic vinegar
2 teaspoons Dijon mustard
1 teaspoon maple syrup, honey, or strawberry jam
1/4 teaspoon fine sea salt
1/4 teaspoon fresh ground black pepper
1/2 cup (120ml) extra-virgin olive oil, or more to taste
1 tablespoon mayonnaise, sour cream, or crème fraîche, optional to make creamy
Whisk vinegar, mustard, sweetener, salt, and pepper in a medium bowl until well blended.
While whisking, slowly stream in the olive oil until completely incorporated and the dressing has thickened.
Taste and then adjust with salt, pepper, olive oil, or sweetener as needed. To turn it into a creamy dressing, whisk in mayo (sour cream or crème fraîche).
