Guides

Some questions are not about a spice. These are the ones SpiceHQ answers directly, each assembled from sourced sections and each stating what it does not cover.

All guides

  • American spice traditions, and why there is no single answer

    What spices are used in American cooking?

    The regional seasoning traditions of the United States, treated separately because they developed separately, with the spices and blends SpiceHQ holds records for in each.

  • The Columbian Exchange, and the spices that changed places

    Which spices are American, and how did they end up defining other cuisines?

    Which spices crossed the Atlantic in each direction after 1492, how fast they were absorbed, and why several cuisines are identified by an ingredient they had for only a fraction of their history.

  • Spices for curry, and what the word is hiding

    What spices do I need to make curry?

    What "curry" actually covers, the small set of spices behind the most commonly meant style, and how the regional directions diverge from there.

  • Starting a spice collection

    What spices do I actually need to start with?

    How to think about building a spice collection: what spices do, how cuisines organise them, how to choose for your own cooking, and the mistakes that cost beginners the most.

  • The most expensive spices, and what actually makes them cost

    What are the most expensive spices in the world?

    Why some spices cost hundreds of times more than others, which ones consistently sit at the top, and why any exact price list is out of date before it is published.

  • Herbs and spices: what actually separates them

    What is the difference between herbs and spices?

    The leaf-versus-everything-else rule is a good working distinction and not a scientific one. This explains where it comes from, where it breaks, and why the ingredients that break it are the interesting ones.

  • How spices actually create flavour

    Why do spices need to be bloomed, toasted or ground?

    The chemistry behind blooming, toasting, grinding and timing, explained once rather than repeated on every profile. Why fat matters more than heat, why a ground spice fades and a whole one does not, and why burnt spice is bitter rather than strong.

  • Making and keeping your own spice blends

    How do I make my own spice blends, and how should I store them?

    How to build a blend from whole spices, why ground spices fade so much faster, how to store what you make, and how to grind without special equipment.

  • Spice adulteration, and what you can actually detect

    What is spice adulteration and how would I know?

    What adulteration means, the forms it takes, which spices carry the most documented risk, and a clear account of the limits of home detection — including why several popular tests do not do what they claim.

  • Spices and health: what the evidence actually supports

    Are spices good for you?

    A guide to reading spice health claims: why the literature looks stronger than it is, what the difference between a capsule and a curry does to every finding, and the small number of results that hold up.

  • Spices and pets: what the veterinary evidence covers

    Can dogs and cats eat spices?

    What veterinary sources actually establish about spices and companion animals: the Allium mechanism, why cats and essential oils are a specific problem, and why an absence of evidence about a spice is not a safety clearance.

  • Spices in pregnancy: what is actually established

    Are spices safe during pregnancy?

    Why the pregnancy question has almost no per-spice answers, which three compounds are genuinely dose-relevant, and how to tell a supplement concern from a cooking one.

  • The spice routes: networks, not a road

    What was the spice route and why did it matter?

    How the spice trade actually worked — the maritime and overland networks, the monopolies built on a handful of crops, and the violence that followed European entry — with the simplifications the popular story depends on.

  • Whole or ground: which spices are worth grinding

    Should I buy whole spices or ground ones?

    A ranked, mechanism-based answer rather than a rule. Which spices genuinely reward a grinder, which do not, why the difference is so large, and the handful of cases where buying ground is actively the better choice.
