Put one scallop shell on the table and look at it twice. Look at its rim first: it runs in and out in small even curves instead of a straight line. Now turn it over and look at the hollow: it is a small dish, deep enough to hold food and strong enough to go into a fire. The shell's rim is where the shape meaning comes from, and the shell's hollow is where the cooking meaning comes from. One object, two things it is good for.
From the word’s history
Our Wiktionary evidence gives scalloped as scallop plus -ed, and adds that in the cooking sense it first meant a seafood dish baked and served in a scallop shell, and is only now used more generally. That single note explains both branches without needing any guesswork.
手上的 Wiktionary 資料說 scalloped 是 scallop 加上 -ed，並且註明：在料理的意思上，它本來指裝在扇貝殼裡烤、也用殼盛著上桌的海鮮菜，後來才擴大到一般食物。這一條註解剛好把兩支用法都說清楚了，不必再猜。
