I am on a budget this Christmas, and was thinking of gifting my homemade salad dressing in a nice glass bottle, along with various other homemade goodies. My question is my dressing is made with fresh garlic and I remember reading somewhere that you had to be careful with garlic and oil......? I certainly don't want to poison my friends and loved ones, anyone had any experience with this? How long will the dressing keep? Is there any special sealing or bottle that needs to be utilized (was just going to use glass bottle from the .99 cent store and a screw on cap). Any guidance is very much appreciated.
