What I learned from my old friends Klaus and Dorle who were both busy teachers and were rising a family with four young children at the time is that it is efficient and saves time to prepare in advance. They used to always have a bottle of home made Balsamic vinaigrette dressing ready to go in their kitchen. I adopted this habit and added a bottle of my own raspberry vinaigrette.
If you want to do the same or if you want to prepare a nice present from your kitchen for a friend just prepare the dressing, then download and print one of the labels and glue it onto an empty vinegar bottle.
Both vinaigrettes go well with a toss of leaf lettuce with fruit, nuts and cheese.
