Need: Boiled Blue Cheese Dressing Recipe....

The reason I'm trying to make my own is because the prepared jars from the grocery taste tooooo chalky. I made some last night by using an old boiled dressing recipe, but it wasn't a good as I want ...

First the recipe called for dry mustard - I'll should have left that out totally

Second the recipe included sugar - didn't taste right with sugar

Third - I could taste the flour used to thicken, so I should have used corn starch

If you have a tried and true recipe, would you please post it for me.

Thank you,

Judy
