01 - Rinse the dandelion petals thoroughly in cold water, ensuring all dirt and debris are removed. Gently pat dry with a clean kitchen towel.
02 - Place the cleaned dandelion petals in a heatproof bowl. Pour 2 cups of boiling water over the petals, cover tightly, and let steep for 10 minutes to extract the floral flavors.
03 - Pour the dandelion infusion through a fine mesh sieve into a separate container, discarding the spent petals. Allow the liquid to cool slightly before proceeding.
04 - In a large pitcher, combine the warm dandelion infusion, freshly squeezed lemon juice, and your chosen sweetener. Stir vigorously until the sweetener has fully dissolved.
05 - Add the remaining 3 cups of cold water to the pitcher. Taste and adjust sweetness as desired, adding more sweetener if needed.
06 - Refrigerate the lemonade for at least 1 hour to allow the flavors to meld and the beverage to chill thoroughly.
07 - Pour the chilled dandelion lemonade over ice-filled glasses. Garnish each glass with a lemon slice and a few extra dandelion petals if desired.
