50 free Garlic trivia questions with answers — food & drink quiz, new questions added Aug 2026.
This garlic trivia quiz covers everything about the world's most pungent bulb. It starts with the plant itself: what genus it belongs to, where it is native, why crushing a clove is what releases the smell, and what a garlic scape actually is. It moves through the kitchen, with questions on toum, aioli, skordalia, black garlic, garlic bread, green garlic and how to keep garlic from turning blue in the pickling jar. History and folklore get their share: the garlic found in Tutankhamun's tomb, the Greek offerings to Hecate at crossroads, the Mishnah's 'garlic eaters', the Korean bear who became a woman on a garlic diet, the Israelites longing for it in the wilderness, and the Central European belief that it wards off vampires. There are also questions on where garlic is grown today, why milk beats water for garlic breath, and what happened to the Gilroy Garlic Festival. Every answer has been checked against Wikipedia's articles on garlic and its relatives and the sources they cite, and each question quotes the sentence that supports it.

Q 01Garlic belongs to which plant genus, alongside onions, leeks and chives?
Allium
Its scientific name is Allium sativum; shallots, Welsh onions and Chinese onions are close relatives too.
Q 02To which region is garlic native?
Central Asia
It has since naturalised across Mediterranean Europe and China, and at least 120 cultivars come from its homeland.
Q 03Which country produced about 73% of the world's garlic in 2024?
China
World production that year was around 30 million tonnes.
Q 04A typical garlic bulb is made up of roughly how many cloves?
10 to 20
The cloves nearest the centre are symmetrical; the outer ones tend to be lopsided.
Q 05What triggers the sharp flavour and smell of garlic?
Damaging the plant's cells
Enzymes in the cell vacuoles break down stored compounds only when a clove is chopped, chewed or crushed, which is why a whole roasted clove is sweet.
Q 06Which compound is most responsible for the 'hot' sensation of raw garlic?
Allicin
It opens the same heat-sensing receptor channels that chilli does, and cooking destroys it.
Q 07What element gives garlic its pungent odour and flavour?
Sulfur
Among all the alliums, garlic has by far the highest concentration of these compounds, which is why it out-punches onions and leeks.
Q 08Which volatile compound, carried from the blood to the lungs and skin, causes lingering garlic breath?
Allyl methyl sulfide
Because it is released from the blood for hours after digestion, brushing your teeth barely helps.
Q 09According to studies, which drink neutralises garlic breath best when taken with the garlic?
Milk
Mixing it in the mouth before swallowing works better than drinking it afterwards; the fat-and-water combination is the key.
Q 10Why does garlic sometimes turn green or blue when pickled?
Sulfur compounds react with amino acids to form coloured pyrroles
The three-ring molecule looks blue and the four-ring one green, like chlorophyll, and all of them are safe to eat.
Q 11What are the two main subspecies of cultivated garlic?
Hardneck and softneck
Hardneck types suit cooler climates and give big cloves; softnecks grow nearer the equator with small, tightly packed cloves and are the ones you can braid.
Q 12So-called elephant garlic is actually a variety of which plant?
Wild leek
Its Latin name marks it as a leek, not a true garlic, which is why it tastes so much milder.
Q 13How is almost all commercial garlic propagated?
By planting individual cloves
The method is called division; sexual propagation is possible but hardly ever used.
Q 21Which Roman naturalist listed the conditions garlic was thought to cure in his Natural History?
Pliny the Elder
Galen, a century later, went further and called garlic the 'rustic's theriac', a countryman's cure-all.
Q 22In the Gojoseon foundation myth, a bear became a woman by eating only garlic and mugwort for how many days?
100
The diet was 20 cloves of garlic and a bundle of Korean mugwort; a tiger who tried the same gave up.
Q 23Central European folklore held garlic to be a ward against which creatures?
Vampires, werewolves and demons
It could be worn, hung in windows, or rubbed on chimneys and keyholes to keep them out.
Q 14What is a garlic scape?
The immature flower stalk of a hardneck
Growers snap them off so the plant puts its energy into the bulb, then sell them to be stir-fried like asparagus.
Q 15Single-clove garlic, also called solo or pearl garlic, originated in which Chinese province?
Yunnan
It forms when garlic is grown without the cold spell (vernalisation) needed to make a multi-clove bulb.
Q 16The word 'garlic' comes from Old English words meaning what?
Spear leek
'Gar' was a spear, a reference to the shape of the leaves.

Alaska
It is hardy through USDA zones 4 to 9 and likes loose, dry, well-drained soil in full sun.

Hecate
Theophrastus records the practice in his sketch of 'The Superstitious Man'.

A Levantine sauce of garlic crushed with olive oil
The word simply means 'garlic' in Arabic, and the sauce is the classic partner for shawarma.
Q 28Emulsifying garlic with olive oil produces which sauce?
