Jamu Kunyit Asam & Teh Jahe
(jah-moo koon-yit ah-sahm & teh jah-heh)
Masuk Angin: Mother's Magic Potions
When the Midwest winter chill sinks into your bones, bringing that heavy, aching lethargy Indonesians call masuk angin (trapped wind), a pill won't save you. You need grandmother's magic: a duo of potent, uncompromising elixirs designed to sweat out the cold and settle the stomach. First is Jamu Kunyit Asam, a tangy, earthy turmeric-tamarind potion that demands fresh roots and patience. The second is Teh Jahe (known traditionally as Wedang Jahe), an intensely spicy ginger brew that forces you to bypass watery American supermarket ginger by roasting it over an open flame and violently smashing it to extract every drop of essential oil. This isn't spa water; this is Javanese medicine, straight from the source.
Before you start
Protect your kitchen from turmeric stains.
Fresh turmeric will permanently stain your hands, cutting boards, and counters a brilliant yellow. Wear gloves if you have a meeting tomorrow, and wash your blender immediately after use.
Ingredients
- fresh turmeric root7 oz
- seedless tamarind paste3 1/2 oz
- palm sugar10 oz
- kosher salt1/2 tsp
- mature ginger root4 oz
- lemongrass2 stalks
- water10 cup
Method
- 01
Pulverize the fresh turmeric for the Jamu.
In a blender, combine the scraped turmeric roots with 2 cups of the water and blend on high until completely smooth.
- 02
Simmer the golden tonic to remove the raw bite.
Transfer the puree to a medium pot with 4 more cups of the water, the tamarind paste, 8 ounces of the chopped palm sugar, and the kosher salt. Bring to a gentle boil, then reduce the heat and simmer for 15 minutes to cook out the harsh, raw earthiness of the fresh root.
- 03
Strain and reserve the Jamu.
Pass the hot liquid through a fine-mesh sieve lined with cheesecloth or a nut-milk bag into a large pitcher, pressing hard to extract all the liquid. Discard the solids. Serve hot to sweat out a cold, or chill to drink over ice.
- 04
Begin the Teh Jahe by blistering the ginger over an open flame.
Place the whole, unpeeled ginger directly onto your gas stove grate over a medium flame. Turn with tongs until blistered, slightly charred, and fragrant, about 5 minutes. This caramelizes the sugars and unlocks the deep, medicinal heat needed to compensate for mild American ginger.
- 05
Scrape and violently smash the aromatics.
Once cool enough to handle, scrape off the charred skin with the edge of a spoon—never a knife, which wastes the potent oils just beneath the skin. Place the ginger and the thick bottom halves of the lemongrass on a sturdy board and smack them hard with a heavy cleaver or mallet until splintered and flattened.
- 06
Brew the ginger elixir.
In a pot, combine the smashed ginger and lemongrass, the remaining 4 cups of water, and the remaining 2 ounces of palm sugar. Simmer gently for 20 minutes until the liquid turns deep amber, extracting every bit of fiery gingerol from the ruptured roots.
Notes
The secret to American supermarket ginger.
American ginger (Jahe Gajah) is watery and mild compared to the fiery small roots of Indonesia. The 'bakar dan geprek' (roast and smash) method is absolutely mandatory here to extract enough heat and complexity for a proper cure.
Never use dried turmeric powder.
Powdered turmeric will yield a gritty texture and completely lacks the vibrant, floral earthiness of the fresh rhizome. If you can't find fresh root at the market, don't make the Jamu.
