Lotus Garlic Vinegar (Purple Garlic Steeped in Rice Vinegar)

Why people make this

Purple-skinned garlic — sometimes sold under the poetic name “lotus garlic” (he hua suan) because the large purple cloves arranged in the bulb resemble the petals of a lotus flower — contains higher concentrations of allicin than ordinary white garlic, along with stronger antioxidant activity. Allicin is the primary bioactive compound in garlic that research links to anti-inflammatory, antimicrobial, lipid-lowering and cholesterol-reducing effects. Purple-skinned varieties are available at Chinese or Asian grocers and online.

Steeping garlic in rice vinegar draws out these compounds into an accessible daily tonic. One teaspoon a day in warm water is all that is needed. The addition of rock sugar tempers the sharp, throat-catching intensity of the raw vinegar and makes the daily dose genuinely pleasant to take.

Method

1. Do not wash the garlic — moisture can introduce bacteria and spoil the preparation. Peel all the cloves and trim off the root ends.
2. Place the peeled cloves into a clean, dry glass jar until it is about half full.
3. Pour in the rice vinegar until about 80% full.
4. Add the rock sugar.
5. Place in a cool, shaded spot. Gently swirl or shake the jar each day.
6. Continue until the rock sugar fully dissolves — usually 3–7 days.
7. The preparation is ready to use after steeping for one full month.
8. To use: take 1 teaspoon daily, diluted in a small glass of warm water.

Nourilo’s Tips

Do not be alarmed when the garlic cloves turn blue-green in colour after about a week — this is a perfectly normal chemical reaction involving the allicin compounds and is not a sign of spoilage. After a full month of steeping, the cloves will return to something close to their original colour. The blue-green phase is simply chemistry at work and is harmless. Do not discard the preparation.
