Final answer:
A royal English breakfast latte combines English breakfast tea, steamed milk, and often vanilla or lavender syrup, serving as a tea-based variation of a latte.
Step-by-step explanation:
A royal English breakfast latte is a beverage that typically blends the rich flavors of a traditional English breakfast tea with steamed milk and a touch of syrup for sweetness, very much like a classic cafe latte but with tea instead of espresso. The specific ingredients can vary, but commonly, this latte is made using a strong brewed English breakfast tea, frothed or steamed milk, and sometimes vanilla or lavender syrup to enhance its royal character. It is a modern twist on the classic tea-drinking tradition in the United Kingdom.
