Hot water with a wedge of lemon (squeezed); a couple of slices of fresh ginger; one dried chili pepper whole (I still have a bunch from last year’s garden)–or use a dash of cayenne; stevia or agave nectar to taste. Spicy, astringent, and sweet all at the same time. (This also makes delicious cold lemonade in summer).
A couple of other winter hot drink options from Cate Stillman–ayurveda practitioner and educator and certified Anusara yoga instructor: hot water with either a little bit of turmeric or a little cinnamon.
