In-N-Out Burger announces ingredient changes for buns, salt, and ketchup

In-N-Out Burger has announced changes to the ingredients of several staple menu items, including buns, salt, and ketchup, in an effort to provide “the freshest, highest-quality food possible.”

Key updates include the removal of sesame flour from buns in locations across ten states, the replacement of iodized salt with sea salt in seasoning packets, and a change in ketchup recipe to use real sugar instead of high-fructose corn syrup.

The announcement has drawn mixed reactions from customers. Some diners expressed dissatisfaction on social media, noting that the new buns feel more crumbly and fall apart easily. Others criticized the removal of iodine from the salt, citing its nutritional importance for thyroid health.

Conversely, many customers welcomed the changes. Supporters praised the removal of sesame flour as a significant benefit for families managing severe sesame allergies. Others expressed approval of the move away from high-fructose corn syrup in the ketchup.
