For those who can't make it to London, what are the best ways to enjoy a cup of tea at home?

The most important thing is to make sure you follow the brewing instructions. That sounds so simple, but really is something that people skip on. For example, in the UK, we drink black tea all the time. If you drink green tea, people usually make it in the same way. And that's wrong. It really affects the taste. It can make green tea very bitter.

Also, knowing what you shouldn't put milk into. I've seen people put milk in Darjeeling, which is a big no-no [due to its delicate flavour]. These things seem so basic but will really make a big difference in how it should taste.

Final question: on a scone – jam first or cream first?

I put cream first. But it's personal preference. Unless you're in Cornwall [jam first] or Devon [cream first], where people get very heated about this topic. I've had people tell me that I'm wrong.
