Q1. Can I use honey instead of corn syrup?

I totally get wanting to swap ingredients, but corn syrup's the secret to preventing crystallization. Honey can make the brittle chewy and burn easier—trust me, I learned this the hard way. If you must substitute, try golden syrup or agave, but the texture won't be quite the same.

Q2. My brittle turned out too chewy—what went wrong?

Oh honey, you probably didn't hit that magic 300°F mark! The temperature is everything for that perfect snap. Next time, double-check your candy thermometer's accuracy (test it in boiling water—it should read 212°F). And don't stir after the sugar dissolves—that can cause crystallization.

Q3. Can I make this without a candy thermometer?

I wouldn't recommend it—this is one time where winging it leads to heartbreak (and sticky teeth). Thermometers are cheap insurance against candy disasters. But if you're desperate, the hard crack stage makes threads that break instantly in cold water.

Q4. How do I keep the seeds from sinking to the bottom?

Here's my trick: stir them in when the syrup hits about 250°F. They'll toast beautifully and stay suspended in the candy. If they still sink, your mixture might've needed another minute or two of cooking before pouring.
