Big Tea is laughing at us with the meagre servings of the equivalent that they sell in shops. Get a shitload of both for a fraction of the price by chopping up a good chunk of FRESH ginger and several shakes of turmeric from a spice rack bottle thing.
Anytime I use ginger in a recipe I keep the scraps, including the outer peel, and make ginger tea from it. Just sieve the bits out before you drink. Not exactly mind-blowing as far as recs go but a little bit of extra fun while cooking :)
