Bitterkoekjes refer to Dutch macaroons which are soft and chewy. It is said that they taste like alcohol-free Amaretto di Saronno. Bitterkoekjes ar used to make Bitterkoekjespudding, a Dutch dessert. Bitterkoekjes is pronounced "bee-tuhr-kook-yuhs" Note: I have a cousin in Amsterdam, perhaps one of these days I will ask her to send down here in Germany Bitterkoekjes.
