A crucial element in this sauce is the level of heat you desire. Choose your preferred chili peppers wisely, whether it's the fiery Thai bird's eye chili or the milder jalapeno. The heat level can be adjusted by adding more or fewer chili peppers, so feel free to experiment based on your spice tolerance. Remember to handle hot peppers with care and consider using gloves to protect your hands. To enhance the spiciness, you can also incorporate red pepper flakes or a dash of chili oil. Start with a moderate amount of heat and gradually increase it to find your perfect balance.
