Ex-pharmacist Andrea Hasselbacher now makes treats.

After spending years in a laboratory earning a pharmacy degree, Andrea Hasselbacher realized “I really just wanted to make ice cream.” So last September, she traded in a full-time job filling prescriptions at Cambridge Hospital to tend the garden and do the books at Journeyman in Somerville. On Tuesdays, when the restaurant is closed, she takes over the kitchen to turn out homemade ice cream sandwiches that she sells under the name Beakers & Cream. Hasselbacher offers different pairings every week, but “if there’s something that’s really popular I try to make more of that.” So far the leader is maple bourbon ice cream sandwiched in peanut-butter cookies, but her favorite is the blueberry buckle: snickerdoodles and ice cream made with mascarpone cheese, dried blueberries soaked in vodka, and walnut crumble. “I made it first two years ago for a friend’s birthday,” Hasselbacher says. “I’ve loved it since then.” Available for $5 Saturday mornings at the Union Square farmers’ market in Somerville, and the Sherman Market grocery,
22 Union Square, Somerville;
$6 at backbar in Somerville, or www.beakersandcream.tumblr
