To brew the perfect cup of black tea, follow these steps: 1) Use fresh, high-quality black tea leaves or tea bags. 2) Heat fresh, filtered water to a rolling boil. 3) Use about 1 teaspoon of loose tea or 1 tea bag per 6-8 ounces of water. 4) Pour the boiling water over the tea leaves or bag. 5) Steep for 3-5 minutes, depending on your desired strength. 6) Remove the tea leaves or bag. 7) Add any desired sweeteners or milk after steeping. For best flavor, avoid over-steeping or using water that is too hot or too cool.
