It's baking season! And, plenty of the recipes around this time of year use lots of spice (cinnamon, cloves, nutmeg,etc.). Since ground spices lose flavor after about six months and chances are you won't use a whole jar that quickly, consider buying whole spices next time. For example, in the case of nutmeg, it will stay potent for up to 2 years and you can easily grate just the amount you need each time. Just use a fine grater and add the fresh nutmeg sparingly - it will taste stronger than the pre-grated, jarred kind.
