1 tsp ground nutmeg = 1 tsp ground mace
Mace is the lacy aril that grows around the nutmeg seed on the same fruit, so it carries nearly the same aromatic compounds in a lighter form.
Trade-offSlightly more delicate and a touch more peppery, with a pale orange colour that shows in a white sauce.
1 tsp ground nutmeg = about 1/2 a whole nutmeg, finely grated
A whole nutmeg yields roughly two to three teaspoons grated, and grating it to order gives you volatile oils that a jar of pre-ground has been losing since it was packed.
MethodGrate directly over the pan on the finest rasp you have, at the end of cooking.
Trade-offMarkedly more fragrant than the pre-ground spice. Pre-ground nutmeg fades within a few months and whole nutmeg keeps for years.
Nutmeg is genuinely toxic in large doses — several whole nutmegs at once causes serious poisoning. This is a spice used a pinch at a time, which is also how it tastes best.
Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter — confirm with the manufacturer or your clinician rather than relying on a substitution chart.
