For example, when taking out the ovaries it is very easy to break them, and the cooks doing the processing work have to sew them back up with chicken-gut as fine as silk thread. Or take drying. It just wouldn't do to use clay-oven drying--that would leave a clayey or earthen taste. Only those bits stretched out under the sun count.
例如，烏魚子取下卵巢後容易破損，加工的師傅必用膜薄如絲的雞腸線縫補，烘乾過程中，用乾燥機不行，因為會殘留泥土味，一定要豔陽曬過才算。
