Submerge a mason jar in a pot full of water and bring to a boil. Meanwhile, heat the olive oil to 350°F.
Carefully remove the mason jar from the water with tongs. Ensure no water is left in the jar, then add the red pepper, jalapenos, and garlic. Pour in the hot oil. Allow to cool and infuse for at least 2-3 hours.
Once cooled, strain the oil and serve.
