Nutmegs are hard ovate seed kernels. These kernels are gray-brown in color and mostly smooth to the touch, but have lightly furrowed surfaces. They are highly aromatic in their whole form, but even more so when grated or ground for use as a warm, slightly sweet spice.
Best known for adding complexity and sweet pungency to confections, pies, and other baked goods, nutmeg also can add a warming kick to roasted fall vegetables or savory breakfasts. Along with cinnamon, its aromatic sweetness can allow for less actual sugar in a recipe while still delivering a sugary taste.
