For a while, I was obsessed with watching TLC’s show, Extreme Cheapskates.  In this show, people go to revolting, albeit sometimes creative, extremes to save money.  Surprisingly, I picked up a good salad dressing tip from one of the episodes.  🙂  When you finish a jar of jam, before you wash the jar and recycle it, make a salad dressing in the still-slightly-jammy jar.  This will not only add sweetness and a hint of fruit flavour to your dressing, it will also save you from having to wash additional dishes.  Of course, this also reduces your food waste.

To make your salad dressing:  Add some vinegar/lemon juice, olive oil, and mustard powder/dijon mustard to the almost empty jam jar.  (Note:  A good starting ratio is 1:5 for vinegar/lemon juice to extra virgin olive oil.  The mustard helps emulsify the dressing.)  Screw the lid on tightly, shake vigorously until the dressing is well mixed, and then adjust the ingredients to taste.  For example, you might want to add additional vinegar, a pinch of salt and/or black pepper, honey/maple syrup, etc.
