Home made blue cheese dressing?

Simple question:

What’s a good substitute for mayo (or anything that tastes like mayo) for making home-made blue cheese dressing?

Personally, I’m a *major mayo aficionado, but GF, well, she looks at it sorta like Dracula looks at a cross.

There’s gotta be some middle ground.

Anyone???

*So much, in fact, that when I was a kid, I had dreams of setting the worlds record at mayo eating–straight out of the jar.

Well, Cook’s Illustrated lists the following recipe for blue cheese dressing. Seeing as it has very little mayo in it, I’d just take it out and add an extra tablespoon of buttermilk and sour cream. If it’s too runny, just add more sour cream.

Seeing as almost all blue cheese dressings are made with mayo, how come your girlfriend likes blue cheese dressing but can’t abide things that have mayo in it? If she’s had BC dressing before, she’s had mayo. I don’t get it.
2 1/2 ounces crumbled blue cheese (about 1/2 cup)
3 tablespoons buttermilk
3 tablespoons sour cream
2 tablespoons mayonnaise
2 teaspoons white wine vinegar
1/4 teaspoon sugar
1/8 teaspoon garlic powder
Salt and ground black pepper

Mash blue cheese and buttermilk in small bowl with fork until mixture resembles cottage cheese with small curds. Stir in remaining ingredients. Taste and adjust seasoning with salt and pepper. Can be covered and refrigerated up to 14 days.

When I do bleu cheese at home, I don’t actually make a dressing. I just put fresh bleu cheese crumbles on the salad. No mayo needed! If the salad’s a little dry, I might do some oil & vinegar too.

Maybe you could use a fat free mayo? Plain yogurt?

You can make a tangy version with ripe blue cheese crumbled into a mustard-based vinaigrette.

Common reason, and purely psychological: If it’s a food you’ve decided you don’t like (mayo, in this case), and you actually see it being used in [whatever the final product is], then you’ve already decided you won’t like the final product.

If it’s already there, but you haven’t seen it being put there, you don’t mind. Parents have been tricking young’uns for years doing this–putting stuff the kids aren’t supposed to like in their food behind their back. It works the same way with adults.

How 'bout some plain yoghurt with the whey removed? You can make it by dumping yoghurt into a coffee filter held in a strainer in the fridge for a couple of hours.
