Found in a bowl of quahog chowder in Falmouth
We went out for our last night in Falmouth to Oysters Too. I ordered a bowl of the quahog chowder. Halfway through, I bit down on something hard. Upon spitting it out I realized it was a whitish ball. I thought that someone's earring must have broken but then googled quahog pearls. Low and behold it was a thing.
Excited to have had a cool story and delicious bowl of chowdah on our last night on the cape.
