The original recipe called for 1 cup of salad oil. I used olive oil, as that's what I use in my salads and I prefer the flavor, but it does solidify in the refrigerator. Another reader uses canola, which will stay more fluid, so you may prefer to that instead. Also, I cut the amount down to 3/4 cup but a couple of people have said they think that's still a bit much, so you may want to use 1/2 cup instead.
