One of the best parts about travel is all of the new food and drink you’re exposed to. Sometimes, you find a food you like so much that you want to take it home with you. Depending on what that food or drink is, though, it might not make it past the TSA.

Every traveler has become accustomed to throwing away bottles of water, soda, and Pedialyte (there’s nothing worse than an in-flight hangover) before going through airport security. There are some liquids with different rules, however, and some banned foods that might surprise you. If it’s not on this list, then it’s good to fly in carry-ons or checked bags, although TSA agents may ask you to take it out so they can take a look at it. These are the TSA food rules to know before you go.

1. Alcohol

Allowances: You’re allowed to bring 3.4 ounces of alcohol (equivalent to a quarter pint or two minis) in your carry-on bag. For checked bags, you can take five liters (1.3 gallons) so long as it’s unopened. Anything under 24-percent ABV isn’t subject to limitations.

Prohibitions: You can’t take anything higher than 70-percent ABV in checked or carry-on bags.

2. Baby food

Allowances: Formula, breast milk, and juice are allowed in checked and carry-on baggage.

Prohibitions: The only stipulation is that the amount in carry-on bags is limited to “reasonable quantities.”

3. Cheese

Allowances: All solid cheese is allowed in carry-on and checked bags, but you might be asked to take it out of your carry-on. Creamy cheese is allowed without restrictions in checked bags.

Prohibitions: You’re only allowed 3.4 ounces or less of creamy cheese in your carry-on bag.

4. Chocolate

Allowances: Solid chocolate is allowed in carry-ons and checked bags. Liquid chocolate is allowed without restrictions in checked bags.

Prohibitions: You’re only allowed 3.4 ounces or less of liquid chocolate in your carry-on bag.

5. Creamy dips and spreads

Allowances: Feel free to take as many dips and spreads as you can eat in your checked bag.

Prohibitions: You can only take 3.4 ounces of creamy dips and spreads in your carry-on.

6. Ice

Allowances: Completely frozen ice and ice packs are allowed in carry-on and checked bags. Dry ice and frozen gel ice packs are also allowed in both.

Prohibitions: The TSA specifies that any ice that’s melted — or, you know, water — can’t be taken in your carry-on. Melted gel ice packs are prohibited in carry-ons as well.

7. Gravy

Allowances: Flying home from Thanksgiving? Bring all the leftover gravy you want in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of gravy in your carry-on.

8. Honey

Allowances: There’s no limit on the amount of honey you can bring in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of honey in your carry-on.

9. Hummus

Allowances: Bring all the hummus you want in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of hummus in your carry-on.

10. Ice cream

Allowances: You can take ice cream in your carry-on and checked bags as long as it’s frozen solid.

Prohibitions: If your ice cream is melty, go ahead and eat it instead of putting it in your carry-on because it’s not making it through. Liquid ice cream is allowed in checked bags, but you might want to just get new ice cream at that point.

11. Jam and jelly

Allowances: Bring all the jam and jelly you can handle in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of jam and/or jelly in your carry-on.

12. Live lobster

Allowances: The TSA is actually very okay with you bringing your live pet lobster in either your checked or carry-on bag. It’s even okay with live lobsters that aren’t your pet that you plan on eating later.

Prohibitions: You have to call your airline to make sure it permits having a live lobster in any carry-ons.

13. Maple syrup

Allowances: Bring all the maple syrup you want in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of maple syrup in your carry-on.

14. Oils and vinegars

Allowances: Bring all the oils and vinegars you can handle in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of oils and/or vinegars in your carry-on.

15. Peanut butter

Allowances: Any amount of peanut butter (and all other nut butters, for that matter) is good in checked bags.

Prohibitions: You can only take 3.4 ounces or less of peanut butter in your carry-on.

16. Salad dressing, salsa, and sauces

Allowances: No limit to the amount you can bring in your checked bag.

Prohibitions: You can only take 3.4 ounces of salad dressing, salsa, and sauces in your carry-on.

17. Soup

Allowances: Bring all the soup you want in your checked bag.

Prohibitions: To the TSA, soup is just as much a liquid as your bottle of water. You can only take 3.4 ounces of soup in your carry-on.

18. Yogurt

Allowances: Bring all the yogurt you want in your checked bag.

Prohibitions: You can only take 3.4 ounces or less of yogurt in your carry-on.
