Explanations: answer key for all 10 questions

Q1: Potatoes were first domesticated in which region?
Answer: The Andes
People in the Andes of today's Peru and Bolivia were growing potatoes around 7,000 to 10,000 years ago. Spanish explorers brought them to Europe in the 1500s.
Q2: What is the main ingredient of guacamole?
Answer: Avocado
Guacamole goes back to the Aztecs, whose word ahuacamolli means avocado sauce. Mexico grows more avocados than any other country.
Q3: Which spice is often called the most expensive in the world by weight?
Answer: Saffron
Saffron comes from the thin red stigmas of the crocus flower, and each flower has only three. It takes around 150,000 flowers to make one kilogram.
Q4: Which nut is the main ingredient in marzipan?
Answer: Almond
Marzipan is made from ground almonds and sugar. The German city of Lübeck has been famous for it since the 1800s.
Q5: Which of these is a true berry in botanical terms?
Answer: Banana
Botanists define a berry as a fleshy fruit that develops from a single flower's ovary, which includes bananas, tomatoes and grapes. Strawberries and raspberries are not true berries.
Q6: Which natural chemical gives chili peppers their heat?
Answer: Capsaicin
Capsaicin tricks pain receptors in the mouth into sensing heat. Piperine gives black pepper its bite, and menthol gives mint its cooling feeling.
Q7: Which grain is used to brew traditional Japanese sake?
Answer: Rice
Sake is brewed from polished rice, water, yeast and a mold called koji. The more the rice is polished, the more delicate the sake usually tastes.
Q8: Which vitamin does the body make when skin is exposed to sunlight?
Answer: Vitamin D
Sunlight helps the skin make vitamin D, which the body needs for strong bones. It is also found in oily fish and egg yolks.
Q9: Which scale measures the heat of chili peppers?
Answer: Scoville
Pharmacist Wilbur Scoville created the scale in 1912. Bell peppers score zero, while the hottest peppers measure in the millions of Scoville heat units.
Q10: In the 1830s, tomato ketchup was sold in the United States as what?
Answer: A medicine
A doctor named John Cook Bennett promoted tomatoes as a cure for indigestion, and ketchup pills were soon sold as medicine. The fad faded, but the sauce stayed.

Food Trivia Quiz – The Stories Behind Our Food

Food is something we all have in common, yet most of us know surprisingly little about where our favorite ingredients come from. The potatoes, chili peppers, tomatoes and chocolate that now feel at home in kitchens worldwide all came from the Americas and spread across the globe only in the last 500 years. Every dish carries a little history with it.

Some food facts are scientific surprises. Botanists say a banana is a berry while a strawberry is not, the heat of a chili pepper is really a chemical trick played on our nerves, and our skin can make vitamin D from sunlight. Knowing why foods taste and behave the way they do can make cooking more fun.

Other facts come from history and trade. Saffron, harvested by hand from tiny crocus flowers, has been valued like gold for thousands of years. Marzipan became a specialty of the German city of Lübeck, and ketchup had a strange early life as a medicine before it became a sauce for fries.

Food is also part of culture and identity. Guacamole goes back to the Aztecs, and sake has been brewed in Japan for centuries. Learning about these traditions is one of the easiest ways to connect with other cultures.

This quiz mixes origins, science and history, with an explanation for each answer.

Our tastes are shaped by biology as well as culture. Humans can detect five basic tastes, sweet, sour, salty, bitter and umami, and much of what we call flavor actually comes from smell. That is why food seems bland when you have a cold, and why the same dish can taste different depending on how it is cooked and served.
