How these work
Every tool here shows its working: what you asked, the method, each intermediate value, what it assumed and where the answer stops being reliable. The full breakdown is free and always visible. Where we do not hold the data to answer, the tool says so instead of applying an average.
Spice quantity converter
Convert between teaspoons, tablespoons, cups, grams and ounces using a density figure specific to the spice and its form — because a teaspoon of saffron and a teaspoon of turmeric are not the same weight.
Blend scaler
Scale any recorded blend version from proportional parts to a target batch weight, keeping the proportions intact and saying plainly which ingredients have no recorded proportion.
Storage and freshness adviser
Check whether a spice is still worth using, from its form, its age and how it has been kept — with the mechanisms behind the answer and an explicit refusal to turn staleness into a safety verdict.
Chilli heat comparison
Compare chilli heat as overlapping bands rather than single numbers, with the reason each range is as wide as it is — and an explicit refusal to say one chilli is twice as hot as another.
Not built yet, and why
Tools follow demand and available evidence rather than being built speculatively. These are the ones that have been considered and deliberately not shipped.
Whole to ground converter
Work out how much ground spice a given quantity of whole spice yields.
Blocked by: Needs measured per-spice yield data, which SpiceHQ does not hold. The commonly circulated generic ratios are not sourced, and publishing one would be exactly the false precision this platform exists to avoid.
Substitute finder
Find a replacement for a spice you do not have, filtered by what you are cooking.
Blocked by: The substitution graph supports this today, but the context filtering that would make it better than the existing substitutes pages needs a wider dataset first. Building it now would duplicate /substitutes without improving on it.
