Unlike standard black or green infusions that rely on Camellia sinensis leaves and brief hot water contact, herbal decoctions require extended thermal extraction to pull flavor compounds from dense seeds and citrus rinds. Water is brought to a full boil at 212 degrees Fahrenheit before heat is removed for the steeping phase, ensuring cellular walls in the celery seed and dried parsley soften adequately. Disregarding the requirement for dried parsley by substituting fresh herbs will introduce excess moisture and grassy chlorophyll notes that unbalance the citrus acidity.
Extracting flavor from celery seed requires thermal energy and time because the volatile oils are trapped within hard seed coats. Letting the mixture sit covered for up to two hours allows water-soluble compounds to fully saturate the liquid without scorching the delicate citrus oils from the nine squeezed lemons. Straining the warm liquid through a fine-mesh sieve removes all particulate matter prior to chilling, which prevents continued, unwanted bitterness from the white pith of the lemon rinds.
