US restaurant brand SONIC Drive-In is set to add Strawberry Mangonada Slush to its Flavorista Favorites drink line-up across the US, in partnership with Mexican company Industrias Tajín.

Inspired by the traditional Mexican mangonada, the new limited-time beverage combines strawberry and mangonada syrup with Tajín Clásico Chili Lime seasoning.

Tajín USA director Javier Leyva said: “At Tajín, we love bringing bold, authentic flavours to every moment, and the new Strawberry Mangonada Slush at SONIC is the perfect way to experience that sweet and tangy kick.

“With the signature zest of Tajín Clásico, this refreshing twist on a classic treat is sure to excite taste buds and add a deliciously vibrant touch to any day, while contributing to a great cause.”

The drink will be available nationwide from 3 March 2025. SONIC app users can order it early.

Available at participating locations, a medium-sized slush is offered at $2.99.

SONIC culinary and menu innovation vice-president Mackenzie Gibson stated: “We’re always looking to bring excitement to our fans with refreshing, craveable and unexpected drinks, and by partnering with Tajín to add their signature seasoning flavour to the Strawberry Mangonada Slush, we’ve done just that.

“By combining the juicy sweetness of strawberries and mango with a hint of zesty lime from Tajín Clásico, we’ve taken classic summer fruit flavours and kicked them up a notch.”

Part of the Inspire Brands group, SONIC operates 3,500 drive-in restaurants across 47 states.

In October 2024, the brand announced the launch of its new winter menu, offering a range of savoury and festive flavours. It had added the Witch’s Brew Slush Float to the Flavorista Favorites drink line-up in the previous month.
