The Spice Cost & Potency Pack
What the jar in your cupboard is actually delivering, and why the large economy bag is so often the expensive one
The shelf-life tracker on this site tells you whether a spice is Fresh, Use soon, or Expired. That is the right shape for a reminder and the wrong shape for a decision, because a jar does not hold full strength for twenty-three months and then stop. Aromatic compounds leave a ground spice continuously from the day it is milled, and the practical consequence is that you quietly use more of it to get the dish you wanted. Nothing announces that. The recipe simply stops working and you correct for it. This pack works the slope instead of the date, and then prices it. Reading the two-year shelf life this site already publishes as a half-life, a jar the tracker still calls Fresh at twelve months has lost nearly thirty percent of its strength — and a level teaspoon of a two-year-old jar delivers the flavour of half a teaspoon. From there it does the thing no spice seller publishes: cost per gram you actually get the use of, rather than cost per gram bought. Because a jar is used across months, what it delivers is its AVERAGE strength over that time, which turns the shelf-edge price into an understatement — and it understates most for the purchase that looks cleverest. Worked through: a 200 g bag priced a third below a 50 g jar per gram ends up costing more per gram of flavour delivered, because it takes four years to finish rather than one. The reversal is not about size at all. It is about time. An entire page is then given over to arguing against that conclusion. The half-life reading is a convention, not a measurement, so the pack re-runs the whole comparison across a range of assumptions and shows exactly where the answer flips: the big bag wins if ground spice keeps just twelve percent longer than the tracker claims. What survives every assumption is separated from what does not, because a pack that only argued one way would not deserve to be believed. Also inside: how much more whole spice is worth paying for at each rate of use, priced from the site's own shelf lives; the bought blend against one you grind yourself; and what a teaspoon really delivers at each jar age. Every figure is computed from the modules behind the site's own calculators. No market data anywhere: no spice prices, no brands, no quoted averages — and money carries no currency symbol, because the figures are yours. It says nothing whatever about food safety: dried spices lose flavour, they do not become dangerous. It ends with a sheet of the ten lines the whole thing runs on, and if you buy from a calculator page your own jar arrives already worked out.
What’s inside
- Potency is a slope, not a date — what a ground spice is doing month by month
- What the shelf-life tracker's three states hide, against the strength actually left
- What the jar in front of you is delivering, averaged across the time you use it
- Why the average is not the midpoint, and why using the midpoint understates every jar
- The sticker is per gram bought, not per gram used — and the gap between them
- Where the economy bag stops being economical, worked on a real comparison
- How much of that conclusion survives if the half-life assumption is wrong
- Whole against ground — how much more whole is worth paying at each rate of use
- The bought blend against the one you grind yourself, priced properly
- What “one teaspoon” actually delivers at each jar age
- Your own numbers — the ten lines the pack runs on, and the order to work through them
