This has the most incredible smell, an intense mix of sweet vanilla and caramel. Thankfully the taste is not as sweet as I believe it would be too overpowering. I found that when piping hot the flavour of tea against the caramel and vanilla were a little at odds with one another. However, when it cooled a bit they balanced very well.
I didn’t try this with any milk, which may have been a mistake. I think the addition of the milk would help to bind the flavours better.
