Notes

For more helpful hints, substitution ideas, slow cooking tips, and other delicious recipe ideas, check out my post above.
CROCKPOT COOKING TIPS: Every slow cooker heats a little differently, so cooking times can vary. Once you know how your crock pot runs (hotter or cooler), you can adjust as needed. 
RECIPE TIPS: Keep the heat on LOW to avoid curdling, whisk every time you check it for a silky texture, and strain after cooking for the smoothest results. Chill before serving if you want a thicker, richer eggnog.
VARIATIONS: Sweeten with maple syrup for deeper flavor, swap in chai spice for a different warm-spice blend, add a split vanilla bean for stronger vanilla notes, or use half-and-half to lighten it.
SERVING SUGGESTIONS: Serve warm straight from the crockpot, chill and pour over ice with a sprinkle of nutmeg, spike with your favorite spirit for adults, or use leftovers for lattes, French toast, or holiday baking.
