Idukki Cloves (Grambu): Uses, Quality Check & Storage

Small bud, big aroma – how to pick, use and keep the best grambu from the Idukki hills.

Short answer: Idukki cloves (grambu in Malayalam, laung in Hindi) are the dried flower buds of the clove tree, grown in the cool, misty hills of Kerala. Good cloves are plump, dark reddish-brown, have an intact round head and release a little oil when you press them with a fingernail. Use 2–4 whole cloves in a family-size biryani or curry, 1–2 in a cup of masala tea, and store them in an airtight glass jar away from the stove.

What are Idukki cloves?

A clove is not a seed or a stick – it is the unopened flower bud of the clove tree, picked by hand when the buds turn pinkish-red and then sun-dried until they become dark brown. Kerala, especially the Idukki high ranges, is one of India's best-known clove-growing areas. The cooler climate and rich soil help the buds develop a strong, warm, slightly sweet aroma that Kerala cooks love in biryani, meat curries, ghee rice and spiced tea.

The aroma comes mostly from natural essential oils in the bud. That is why freshness and correct storage matter so much: once the oil fades, the clove looks the same but tastes flat.

How to check clove quality at home

You don't need a lab to tell good cloves from tired ones. Try these simple checks:

1. Look: buds should be fairly uniform, dark reddish-brown, with the round head (the bud cap) still attached. Too many headless stems or broken bits means lower grade.
2. Press: push a fingernail into the stem. A fresh clove releases a tiny trace of oil and a sharp smell.
3. Smell: open the jar – a good clove hits your nose immediately. Weak or musty smell means old or badly stored stock.
4. Water test: drop a few cloves into a glass of water. Oil-rich cloves tend to sink or float upright with the head up; cloves that lie flat on the surface are often dry or exhausted.
5. Weight: good cloves feel slightly heavy for their size, not papery.

Good cloves vs poor cloves

How to use cloves in a Kerala kitchen

• Biryani and ghee rice: fry 3–4 cloves in ghee with cinnamon, cardamom and star anise before adding onions. This is the base of Malabar-style biryani aroma.
• Chicken, mutton and beef curries: 2–3 cloves in the tempering, or ground into the garam masala.
• Masala chai and Kerala spiced black tea: crush 1–2 cloves with a pod of cardamom and simmer with the tea.
• Homemade garam masala: lightly dry-roast cloves with other whole spices, cool and grind in small batches.
• Pickles and Christmas baking: a pinch of ground clove adds warmth to plum cake and spiced fruit mixes.

How much clove is enough?

Cloves are strong, so think of them as a seasoning, not a snack. In everyday cooking, 2–4 whole cloves for a family pot of rice or curry, and 1–2 cloves in a cup of tea, is plenty. Some people chew one clove after meals as a breath freshener – that is a traditional habit, but avoid chewing many at once, and never use concentrated clove oil undiluted. If you are pregnant, on regular medication or have a health condition, talk to your doctor before using clove in larger, medicinal-style amounts.

Storing cloves in hot, humid Kerala weather

• Keep whole cloves in an airtight glass jar with a tight lid – plastic boxes can absorb the smell.
• Store away from the stove, sunlight and the steam of the pressure cooker.
• Always use a dry spoon; even a drop of water during monsoon can bring mould.
• Grind clove powder in small amounts (enough for 2–3 weeks); powder loses aroma quickly.
• Stored well, whole cloves keep good aroma for many months. Check the pack's best-before date.

Frequently asked questions

What is clove called in Malayalam?

Clove is called grambu (ഗ്രാമ്പൂ) in Malayalam, laung in Hindi and kirambu in Tamil.

Why are Idukki cloves special?

Idukki's cool, high-altitude climate helps clove buds develop a strong, warm aroma, which is why Kerala cloves are popular with home cooks and spice buyers.

How can I check if cloves are fresh?

Press a clove with your fingernail – fresh ones release a little oil and a sharp smell. Also look for intact heads and an even dark reddish-brown colour.

How many cloves should I use in biryani?

For a family-size biryani (about 1 kg rice), 3–5 whole cloves along with cinnamon, cardamom and star anise is usually enough.

Can I chew cloves every day?

Chewing one clove after a meal is a common traditional habit. Avoid chewing many at a time, and ask your doctor before using cloves in large or medicinal amounts.

How long do whole cloves last?

Stored airtight in a cool, dry place, whole cloves keep good aroma for many months. Powder fades much faster, so grind small batches.
