i love it all, with honey, concentrated sweet milk, milk, if the matcha is too bitter to drink on its own. they help mask the grassy bitterness in cheaper matchas.
but for higher grade matcha i just leave it alone because it is already wonderful and i like the taste, it would be a shame if i miss the special umami aroma. it will be creamy like foam if prepared goodly with the bamboo whisk.
i love matcha au lait with heated milk and sugar or honey. i like with ice and shaken cold matcha is delicious. there are even matchas specific to prepare cold. there are instant sweet matcha powder drinks, that is easy to make & easy to dissolve.
there is no wrong way to prepare your matcha! make and enjoy as you please! don't force yourself to drink something you don't like for others' sake or tea blasphemy. i put in cakes and desserts too. get creative!
in the end, i believe to appreciate the matcha in its truest form is matcha + hot water. also because matcha flavors in the powdered fine grounded leaves are not released until adding hot water that is a certain temperature like 70 to 85 degrees depending on the matcha... but then that is a different topic, technique, taste buds, and price tag all together...
