- 8 cups water (2 liters)
- about a dozen black peppercorns
- 3-4 Oz of a liquid sweetener (103.5 ml)
- one small but decent sized piece of sliced ginger, sliced up into coins. Dried/ground ginger can also be used, somewhere around 1-2 tablespoons (7-14 grams)
- 1 cup fruit (dried dates, in my case)
- 1/2 cup Balsamic vinegar (120 ml)
Bring the water to a boil. While that's going on, juice the citrus and try to peel or zest it so you don't have the pith. Throw peel and juice in with other ingredients. Put on low heat. Whisking will help ingredients incorporate, especially if using dried ginger. You may start serving once it has an aroma.
This can be served hot or cold, and some like to put a small amount of rum in their switchel. You can also remove the whole spices and blend the switchel after it has cooked for an hour or so so it has a more homogeneous texture.
Reasons for adding the vinegar are that some vinegars, including Balsamic vinegar and apple cider vinegar, contain electrolytes and can help clear phlegm. Similarly, ginger and other warming spices can help with mucus and a sore throat.
What sweetener you use varies. I used a waffle house syrup packet and some date syrup. Traditionally, you'd use molasses, maple syrup, birch syrup, or something else along those lines. The citrus and additional fruit aren't necessary. The basic switchel is just water, ginger, vinegar, and sweetner. The citrus helps if you're feeling ill, and the additional fruit is just more flavor. I've seen blueberries and blackberries added most often, but you could even try things like peaches or figs. Go wild.
If you're unsure about your vinegar tolerance, I'd recommend adding all the other ingredients to the pot and letting it start to get an aroma, then taking a cup of that and adding a teaspoon of your vinegar. If you enjoy it, add a teaspoon of vinegar per cup of water (8 total), and gradually increase until you get your desired flavor. If you accidentally added too much, either add in more water or more sweetener. If you like, you can even try mixing this with club soda (as is common for shrubs, a similar kind of vinegar based drink).
