In a small-medium bowl add the vinegar.

Using a whisk, whisking quickly, add olive oil in slowly. If the suggested amount isn't enough add more to suit your taste. You should taste the oil/vinegar mixture as you go. You want a little bit of a bite. It's shouldn't be too strong. You still have to add more stuff.

Add the honey while mixing. Taste. It shouldn't be very sweet.

Add the strawberry preserves and yogurt and pepper. This is where you'll tailor it to what you want. A little sweeter add more honey or preserves. If you want it creamier add more yoghurt. The yoghurt will also dull the 'bite' from the vinegar.
