In-N-Out fans experienced a major social media frenzy on Tuesday. The popular burger chain announced significant changes to some of its core ingredients.
The California-based restaurant operates across 10 states. Company officials confirmed they removed sesame flour from their buns and switched from iodized salt packets to sea salt.

Management stated the changes reflect an ongoing commitment to quality food. They pointed to a similar decision last year that removed high-fructose corn syrup from their ketchup.
"We remain committed to serving our Customers with the freshest, highest-quality food possible," the company stated in a release. They plan to continue building on those quality standards for years to come.
The ingredient updates quickly sparked a mixed reaction online. Many customers praised the sesame removal, while others complained about the new salt packets.
"This is great news!" one Facebook user wrote. The customer explained that a sesame allergy had previously kept them away from the restaurant.
"How great to be able to put In-N-Out back on the list of options," another user added. Removing the allergen opened up new dining possibilities for families.
Corporate representatives did not explicitly state whether the bun modification was made specifically for allergy safety. However, the update comes after federal regulations classified sesame as a major allergen.

Companies previously added sesame to various products to manage cross-contamination risks. In-N-Out adjusted its baking process to eliminate the ingredient entirely.
Meanwhile, the salt replacement drew immediate pushback from patrons. Several customers voiced concerns about losing iodized salt and its health benefits.
"Remove iodine? Sure, because apparently goiters needed a comeback," one Reddit user posted. Critics questioned the nutritional reasoning behind the switch.
Others complained about the physical texture of the new seasoning. "The iodized sticks to the fries better," another Reddit user noted.
Another customer complained about the size of the new crystals on Facebook. They noted that the seasoning used to feel much smoother.
The company has not provided a detailed explanation for ditching iodized salt. Iodized salt has been widely used since the 1920s to prevent iodine deficiencies.
Traditional iodized salt often includes anti-caking agents. Sea salt typically undergoes less processing and lacks those additives.
