To make ranch, you need equal parts mayonnaise, sour cream, and buttermilk. I started with my mayonnaise base, two egg yolks, a squeeze of dijon mustard, a dollop of lemon preserve, but you don’t actually need that. And then a good pinch of salt. Then I just slowly incorporate a neutral oil until it gets nice and thick. Finish it off with a squeeze of lemon juice. And then just taste it to make sure it’s well balanced. And if it needs more salt, add it in. And then the buttermilk, which I make by squeezing some lemon juice into some milk and just let it sit for a few minutes until it becomes sour. I actually removed half of the mayonnaise I made so I could make garlic mayo for something else. Added in two dollops of sour cream on top of the mayonnaise and then just slowly incorporated the buttermilk until I got the consistency I wanted. Finishing off with the seasonings, I did dried dill, onion, and garlic powder and fresh parsley. I think chives go in here as well, but I didn’t have any. And the parsley does not have to be fresh. And there you go. Homemade wrench.
