I use a mini prep food processor for this and it makes it very simple. Pour your oil into small bowl. Add: minced parsley,crushed garlic, add dried herbs and balsamic and whisk. I let stand for about 1/2 hour before serving with Hot crusty bread. Fabulous and EASY!!
There are variations to this as well: Some like it hot!!! Add more red pepper or dash of cayenne pepper. I have also used roasted garlic for people who are not garlic lovers, it gives it a sweeter, mellow garlic taste. Add black olives and puree for a yummy tapenade. Mix it up and find your own way, yummy and good for you!! ;-)
