You can order Mace on Amazon.com!
Mace is the dried, reddish covering of the nutmeg seed. This unique spice is AIP-friendly, so this is what I use whenever I want that nutmeg flavor in an AIP dish. Mace tends to have a more delicate flavor than nutmeg, but it does evoke the same sensory qualities (you just might need to mess with the quantity, depending on the flavor you’re looking for in a dish). As with any spice, but especially one that is AIP-friendly, you’d want to opt for a responsibly-sourced, high quality option whenever possible.
