Why spice blends are best thought of in parts, not grams
Classic spice blends like garam masala or five spice are traditionally passed down as ratios — so many parts of one spice to so many parts of another — rather than fixed gram amounts, because a ratio scales cleanly to any batch size while a fixed recipe doesn't. This calculator keeps that ratio logic intact: each blend is defined by relative 'parts' for every spice, and your chosen total weight is distributed across those parts proportionally.
This means you can make a small 20g jar for a single recipe or a 500g batch to store for months, and every spice's relative proportion to the others stays exactly the same either way.
Why homemade blends often taste better than store-bought
Pre-ground spices lose aromatic intensity over time, sometimes significantly within just a few months of grinding, so a store-bought blend sitting on a shelf for a year is almost always going to taste flatter than a freshly made batch. Making your own blend from freshly toasted and ground whole spices where possible, using a known good ratio, typically produces a noticeably more fragrant result.
It also gives you control to nudge a blend towards your own taste — slightly more black pepper for extra warmth, or reduced chilli for a milder version — while keeping the overall balance recognisable.
Storing a scaled batch properly
Ground spice blends keep their aroma best stored in an airtight container away from direct light and heat, ideally used within two to three months for the best flavour intensity, since ground spices lose potency faster than whole ones. If you're scaling up to a large batch specifically to save time, consider splitting it into a small everyday jar and a larger sealed backup container, rather than repeatedly opening one large container and exposing all of it to air each time.
Frequently Asked Questions
Can I adjust the ratio for a blend to suit my taste?
This tool scales the classic reference ratio for each blend; if you want a different balance, you can note the scaled amounts and manually adjust one or two spices to taste before combining.
Do I need whole spices or can I use pre-ground ones?
Either works — whole spices toasted and freshly ground give the most aromatic result, but pre-ground spices in the same scaled ratio still produce a good, usable blend.
Why do the 'parts' numbers not add up to the total amount?
Parts represent relative proportion, not literal grams — the calculator converts those proportions into actual grams based on your chosen total blend weight.
How long does a scaled batch of spice blend last?
Ground spice blends are best used within two to three months for peak flavour, though they remain safe to use well beyond that, just with reduced aroma.
