Place the oil in a small skillet over medium-high heat. As soon as it gets hot, add the garlic and reduce the heat to medium low. Simmer for 2 minutes. Remove from the heat, and set aside to cool.
Place the butter, lemon zest, lemon juice and garlic mixture in the bowl of a food processor. Process until smooth. Transfer to a large piece of plastic wrap, and roll into a 2-inch diameter cylinder. Wrap tightly, and refrigerate until ready to use.
