Recently, I received an email from a PR representative asking me if I wanted to sample Biscoff cookies, "a European treat that's developed a cult-like following among Americans." The company happens to be opening its first US retail store at San Francisco's Pier 39. While I wasn't familiar with the brand Biscoff, I love European-style cookies, so naturally, I said yes. The cookies, which are sometimes called biscuits, are a flavorful accompaniment to coffee. They are crisp and taste like a cross between a graham cracker and animal crackers. Have you ever had them? Are you a fan?
