Prohibition on foods in gel form
When it comes to carry-ons, the TSA has banned all liquid and gel foods larger than 3.4 ounces (as well as liquids and gels larger than 3.4 ounces that are not foods, such as hair gel, gel pens, and gel ice packs). If the item can be spilled, sprayed, spread, pumped or poured, you should pack it in checked luggage or leave it at home, according to the travel blog Recommend.
