A question about a recipe: Shaved Asparagus and Mint Salad

I wouldn't make it more than an hour or two before. I found that the asparagus got soft after soaking in the vinaigrette and wasn't as tasty left over.

It can be made up to a day or two before, I think it's best made a couple hours ahead so that it has time to absorb the flavor of the vinaigrette. It changes a little in texture as it sits, it's less crunchy the longer it sits, but it's good either way.
