The following recipe is compliments of A. Wells:
The Best Homemade Ginger Tea
Ingredients
Serves: 1-2
1 Tbsp. fresh grated ginger
2 cups filtered water
1 Tbsp. raw honey or pure maple syrup
½ lemon, juiced
Optional
1 cinnamon stick
Camomile flowers
Echinacea tincture
Fresh mint leaves
Pinch of cayenne pepper
Directions
Peel the ginger root with a peeler or with the back of a spoon.
Grate the ginger with a grater/zester. If you slice it, slice it thin and use more.
Infuse the ginger; if you add cinnamon, mint, camomile or cayenne, add it here.
If
you are using a saucepan, bring the water to a boil, add ginger and
turn off heat. Put the lid on it and let it steep for 10 minutes.
If you are using a teapot, add ginger in the teapot and pour boiling water in it. Let it steep for about 10 minutes.
If you are using a saucepan, strain the water to remove the ginger.
Add fresh lemon juice and natural sweetener if you like. Stir and enjoy!
If you want a cold tea, let your tea cool down, store it in the fridge and add ice cubes before serving.
