I've tried making this sweet onion dressing Twice now, and still not as good as your subway dressing., also it looks a lot darker even though I followed the recipe to the T... why is that., is it from the red wine vinegar., HELP, i love your dressing.

I've made this dressing twice now and still doesn't look like the one we get at subway... its much darker., what is wrong now. i love that dressing and I can't make it right with the ingredients here.

Krogers has buttermilk powder in the powdered milk aisle. It is used when one doesn't usually have buttermilk on hand.

I have some that I found in the baking aisle made by SaCo. It comes in a round can type container with a cover.

Okay, I give up... what is buttermilk powder, where do I find it, or what is a substitute?

The Buttermilk powder is just used as a thickner, so instead of buying something you might not use in other recipes, you can substitute corn starch in this recipe.
