For the oil you'll need, olive oil, garlic, rosemary, basil, and a container to store it in. I found this one at Target, but you can use whatever you have as long as it can be sealed.
Start by adding 5 peeled cloves of garlic to your container.
Next, add 4 sprigs of rosemary.
Next, add 5 basil leaves.
I find it helpful to roll the leaves into a tube so that they easily fit into the container.
Lastly, add in the olive oil. Within a day or two, the olive oil will be infused with the flavors of garlic and herbs. Try it with bread, on pasta, or wherever else you please! Keep refrigerated.
