Start by slicing the lemon and apple into attractive, thin slices. I prefer keeping the slices neat because they will remain visible in the finished drink and add a fresh homemade look.
For a cold apple lemonade recipe, pour the gallon of apple cider into a large punch bowl. Add the frozen lemonade concentrate and stir the two ingredients together until they are evenly combined.
Add the sliced lemon and sliced apple directly to the mixture. I like distributing the slices around the bowl so they float throughout the drink instead of collecting in one spot.
If you want a refreshing apple lemonade drink, serve the mixture cold after combining the ingredients. Add a lemon wedge and a cinnamon stick to individual servings if you want a more decorative presentation.
For a cozy version, add the apple cider and lemonade concentrate to a 5- or 6-quart crockpot. Stir them together, then add the sliced apple and lemon.
Cover the crockpot and cook the mixture on low for about 4–5 hours. I find this option especially appealing for autumn gatherings because guests can enjoy the drink warm straight from the slow cooker.
Ladle the warm drink into mugs and add a cinnamon stick if desired. For a cold serving, a lemon wedge alongside the glass gives the drink a simple, fresh finishing touch.
