Black leaf OP blended with freeze dried orange, papaya and pineapple, plus cornflower and calendula petals.
The OP stands for Orange Pekoe.
Brew Temperature: 100C
Brew Time: 2-3 Minutes, but you can play around with this one. If you like a light but really tasty cup you can use the leaves a couple of times (a bit like a green tea) so brew it for less than a minute, or longer for a full cup.
To Milk or Not to Milk? Sure, go for it, but you'll want to brew the leaves for a little longer (depending on taste) for the milk to do its thing.
