After successfully growing tons of Basil this year, and before the first frost comes, I new I needed to get busy and make some pesto. Last year I made it for the 1st time and after a day, it turned a dark green, not to appetizing! So this year I did a little research and found that if I just blanch the basil in boiling water for 15 seconds, then immediately take it out, and put it in an ice bath it stays a vibrant green!! Then all you have to do is squeeze it out, throw it in a food processor, with 1 lg clove of garlic for every 2 cups of basil, 1/4 cup of walnuts (or pine nuts) salt and pepper, and then stream a little EVOO in there and the result is not only delicious, but 4 days later it is sill as green as ever!! It was so easy and so much more flavorful then store bought!! You must try it sometime!!
