I'm a bit of a hoarder - every time I use up mustard or spices, I save the little jar. My roommate thinks I'm crazy but they're perfect for making your own salad dressing. It's so easy, I tell ya! You'll never need the expensive bottled stuff again.
My go-to formula:
ACID + OIL + MUSTARD + SWEETENER + SALT/PEPPER
I like a squirt of mustard, a dash of sweetener, and a 50-50 ratio of acid to oil, but that's on the lighter side. All you do is pour the ingredients into a jar and s~h~a~k~e it up to emulsify and create a smooth, full-bodied dressing. If you taste it and don' t like it, just throw in a little more of whatever you think it needs and shake it up again. It's almost impossible to screw up!
The possibilities are endless! Just use what you have on hand. Any combination of the options below would be delicious:
Acid: Citrus juice (lemon, lime, orange, grapefruit) or vinegar (sherry, champagne, balsamic, rice, etc.)
Oil: Olive, grapeseed, walnut, sesame, peanut, avocado
Sweetener: Sugar, honey, agave, maple syrup, jam, mashed up berries
Extras: Minced garlic/shallots/scallions, chopped herbs, ginger, soy sauce, sesame seeds
