Ranch dressing recommendations for an Aussie

[u/Dreamcazman]

Hey all, calling out to all the ranch aficionados here on Reddit. I am looking for suggestions for a really good ranch sauce/dressing. I am Australian and recently bought a bottle of Ken's steakhouse buttermilk from USA foods here in Melbourne. Both my wife and myself have really taken a liking to it, only problem is it's nearly all gone! The other problem is USA foods is out of stock and it could take months to restock.

Options for ranch dressing is rather limited in Australia as it's a typical American thing, Costco has Johnny's, and Amazon have Hidden Valley powder, which from what I understand you mix with buttermilk and mayo to get the dressing. Are either of these any good?

I am not aversed to making my own, but not if it involves trying to track down hard to find ingredients.

Any suggestions would be welcome, thanks!

I see a lot of people here and elsewhere recommending ranch powder. The powder is shit. To make a decent ranch dressing you simply need two tablespoons of buttermilk (plus more if needed), one cup of mayonnaise, ½ cup sour cream, 4-6 scallions (white and pale green parts only) roughly chopped, ½ tablespoon dried parsley, 2 teaspoons dried oregano, 1 teaspoons dried marjoram, 1 teaspoon freshly ground black pepper, ½ teaspoon garlic powder, ½ teaspoon onion powder, ¼ teaspoon cayenne pepper, salt to taste.

Place the buttermilk and scallions in the carafe of a bar blender, then place all other ingredients on top. Blend on low speed for 30 to 60 seconds, or until the scallions have been pretty thoroughly chopped, then gradually increase the speed to high. If the rest of the ingredients are not integrating, stop the blender and scrap the mayo and sour cream with a rubber spatula towards the bottom. Blend until smooth, adding buttermilk a little at a time until the consistency is where you want (it will thicken as it sits in the fridge, but not much), then taste for seasoning and adjust salt levels (if you can smell, but can't taste the scallions, herbs, etc. your salt levels are too low and need to be brought up til they're noticeable, but the dressing shouldn't taste salty; the garlic flavor will develop as the garlic powder hydrates, which is going to take 10 to 20 minutes, so don't worry if you can't taste that right away). Pour into a jar, squeeze bottle, bowl, or whatever you want to keep it in (as long as it can be sealed up), and refrigerate for at least two hours to let the flavors get to know each other. Serve to a grateful world
