I hope you will let us know if either of these is close to what you remember? And also, how is this type of dressing used?

I have never made this but it looks delicious.

I have been looking for this too love it! I'm from So Cal also... now live in. Missouri

I remember it too! I lived in Santa Barbara County (Lompoc) and I used to get it there too. I think the first recipe might be right. I'll try to make it and let you know. Another one... Clearman's spread, a cheese spread from So Cal. Google it, I found the recipe on line then I found it in Albertson's.

Thanks for the white house dressing receipe. I'm going to try to make it. Let you know!

The White Dressing brings back so many wonderful memories. Thanks for sharing the recipe

I have been looking for this for years as well, lived in So Ca. Needed a dressing with no sugar, found this via my MIL. Was able to get it at Safe Way, but no luck anymore. Love that dressing. Will try these recipes. Thank you.

Hey. We also got it at defalcos. Did you grow up in OB/PL?

Gerard's made White House Dressing, but discontinued it years ago. It made great potato and macaroni salads. It also was,the best on the 24 hour layered salad. I have never found anything to replace it. Why doesn't Gerard's get with it? If they would promote it for the above salads, I think it would be a hit.

What's the thought behind heating the buttermilk???

I grew up in Southern California in the 60's and 70's. I remember my mom buying White house dressing at our local Safeway. We used it on our pork chops. I would also like to find the recipe. Has anyone tried the posted recipes?

We used to by it by the case! Great stuff! I grew up in Long Beach, CA in the 60’s-70’s.

Yes; and I’ve been looking for it for years!!!!Soooooo good!!!

Denise Duvall , me too!!!!

My family grew up on this salad dressing & have searched for the recipe for decades! PLEASE...if anyone has found it, PLEEEEASE email the recipe to me! My email is: humbuggy@yahoo.com

...I can't thank you enough!!!! 😀👍

Have not tried this yet but will as soon as I get home. Gerrards White House was my all time favorite until I started counting calories.

I have been trying to find it as well. We used to put it on Broccolli and other vegies. I’m wondering if it was a So. Cal thing, as it seems that everyone that remembers it was from CA.

I'd love to know how one can simmer buttermilk without it curdling? Happens almost instantly when brought up to any kind of simmer it seems? We used it mostly on Baked Potatoes, nothing like it! I'm cutting this recipe in close to quarters don't need 5 cups, I think it came in a 1 pint jar when they made it and my guess as to why they discontinued is the very short shelf life compared to there other products. Hope it works love me some White House yummm! Guess I'll try room temp buttermilk

Also, can't see the recipe with brown sugar and worshisher sauce being right it was very light like mayonnaise in color, we'll see

Okay folks, no idea why no one else has commented but the first recipe is extremely close to what I remember! Yahoo White House is back! Super easy to make took like 5 minutes, go for it you'll be glad you did

Glad to hear it! I will def give it a try!!!

I think it was discontinued because of short shelf life. The first recipe above is it, exactly! Not the one with Worcestershire sauce

Yes, I loved it! 😢
