on my first night in montreal, i passed by dr.frost and noticed a sign for "macarons givres" and was instantly intrigued. i had no idea what "givres" meant though, so i kept walking. eventually i learned that "macarons givres" are macaron ice cream sandwiches and i absolutely had to check them out. i was greeted by giant day-glo colored macarons with a blob of ice cream inside, they looked like some kind weird frankenversion of the cute, delicate macarons i was used to so i held off on trying one til my last day in montreal.
INSTANTLY HOOKED at first bite! the cookie is a little denser than a "normal" macaron but still slightly chewy and crumbly. they really are freak-ish day-glo colors though and are really awkwardly sized and difficult to bite into. still, it kinda fits the "mad scientist" theme of the shop. you can choose from pre-made macaron combos or mix and match your own creation with their ice cream flavors. they have a stone slab style ice cream with mix-ins, as well as frozen yogurt and shakes.
i loved my first sandwich so much that i went back and bought three more only minutes before i had to catch my bus back to boston (and these babies aren't small!) while wheeling my suitcase and trying to balance my frozen macaron sandwiches i dropped one on the street...and for a moment i considered picking it up. they're THAT good!
