Sieve
Your kitchen sieve can do much more than dust sugar onto your fairy cakes. In fact, it performs a very similar function to a tea strainer.
It’s possible to brew your tea separately, and place the sieve above the cup as you pour. It should catch most of the leaves!
Sieves made from stainless steel or heat-friendly materials are best. Do bear in mind that sieves can be quite bulky though. You might want to do this over the sink, and choose someone with a steady hand! Pouring from a teapot, or a jug with a lip, will give you more control. Always take care around hot liquids.
Slotted Spoon or Fork
If you’re really in a fix, you can simply try fishing out the leaves with a slotted spoon or fork. This can be rather time-consuming though, and it’s certainly not easy to reach all of those pesky smaller leaves! Another option is brewing your tea in a jug, and using your spoon or fork as a barrier for the leaves, whilst you carefully pour the liquid into a separate cup.
