I rarely use bottled salad dressings, as I tend to prefer homemade versions much more. This is my hands down favorite. It is easy to throw together and is so flavorful. This only makes enough for a few dinner salads - only make as much as you need for one meal, as this only keeps maybe a day. Walnut oil and shallots are the two key ingredients here - you can sub any sweet onion for the shallots, but the walnut oil is what gives this its unique flavor. I may vary what types of lettuces and veggies go into a dinner salad, but if I am using this dressing, I always add some crumbled mild feta cheese to the veggies. Walnut oil can be found in bigger grocery store with other flavored oils or in gourmet markets. Walnut oil needs to be kept in the fridge as it spoils quickly at room temp (but lasts ages in the fridge). People have been asking for this one for a while, and yesterday I finally made this with a pen & paper by my side to carefully measure out the ingredients. This will very lightly dress 4 small dinner salads or 2 much larger ones. Enjoy! NOTE: Walnut oil is an extra virgin olive oil infused with the flavor of walnut and has a unique nutty flavor. You may use other nut flavored oils with good results (like hazelnut or macadamia), but just be sure the oil is infused with nut flavor. Something like peanut oil will not work as a substitute for the walnut oil.
