Do I need flaky salt, or can I use kosher salt?
You can use kosher salt. Flaky salt gives a more “everything bagel” finish because you get little salty bursts on top. If using kosher, start with slightly less, then adjust after tasting.
Can I toast the seeds first?
Yes, and it's great if you want extra nutty flavor. Toast sesame seeds in a dry skillet over medium heat until lightly golden and fragrant, then cool completely before mixing so you do not trap steam in the jar. Quick note: toasted seeds can lose freshness a bit faster because the oils are more exposed, so store the jar away from heat and light and use it sooner.
Is dried minced onion the same as onion powder?
No. Use dried minced onion (or dried onion flakes) for the classic texture. Onion powder can make the blend dusty and it sticks differently.
How do I use it on eggs?
Sprinkle it on after cooking. The seeds stay crunchy and the garlic and onion do not taste scorched.
Can I make it without poppy seeds?
Absolutely. Leave them out or replace with extra sesame seeds. The flavor still works, you just lose that little pop.
Is this gluten-free?
The ingredients typically are, but always check labels and facility warnings if you need strict gluten-free. Anti-caking agents are usually not the issue. Cross-contamination is the bigger concern.
Should I grind it?
I would not. Keeping everything whole gives you that classic crunch and makes it a true finishing seasoning.
