Heinz is known for its variety of condiments and sauces, and is now bringing those flavors to customers in the United Kingdom in an unexpected format to celebrate its 150th birthday.

According to news and media website Londonist, the company is teaming up with London’s Hummingbird Bakery for a collection of cupcakes featuring its signature tastes. They will come in ketchup, beans, mayo, salad cream, and tomato soup options.

Each of the six Hummingbird Bakery locations in London will give away 25 of the cupcakes for free (150 total), on a first come, first served basis. Following that, they will be available for purchase for £3.45 each take away/£4.15 eat in.

The Heinz x Hummingbird Bakery cupcakes will be available starting Friday, October 11 for a limited time.
