Your masala chai deserves better leaves
Let's clear something up first: we are not here to reform chai. Chai is perfect. Boiled hard with milk, ginger smashed with the back of a spoon, sugar unapologetic, it's the best thing that happens on Indian mornings and we will not be taking questions.
There is a version of it most people haven't tasted, though, because the tea underneath is an afterthought. The dust in most chai packs contributes colour and astringency and nothing else, so the masala does all the work while the tea just stands there being brown.
Swap in a strong whole-leaf Assam and the base note changes completely. Malt shows up. The ginger has something to argue with. You can back the sugar off by a third because the tea itself carries sweetness, that dark honeyish thing good Assam does. It's the difference between cooking with real stock and cooking with a cube.
The method barely changes. Crush your aromatics as usual, ginger always, plus cardamom, a clove, and black pepper if it's raining. Simmer them in water for two minutes. Add a properly heaped spoon of whole-leaf Assam per cup, more than you'd use of dust, because whole leaves are airy. Simmer for ninety seconds rather than five minutes, since whole leaf gives up its strength more gracefully and turns bitter later than CTC, though it does turn. Milk in, one good boil-up until it climbs the pot, off the heat, lid on, one minute of patience. Strain.
The one adjustment that matters: don't judge strength by colour. Whole-leaf chai brews a shade lighter than dust chai at the same strength, so taste it before you compensate.
Our Assam is picked for exactly this kind of abuse, a second-flush leaf with enough spine to hold its own against ginger. The batch number is on the tin.
