Grrr. I have everything to make homemade toasted coconut marshmallows, except you have to heat the syrup to 240 degrees on a candy thermometer, which I don't have. Anyone know how I can tell when it's ready? Like let it boil for a certain amount of minutes?
TIA!

Re: Help w/ a candy making question!
C&P'd from About.com:
Some cooks prefer to use a candy thermometer and some prefer to use the old-fashioned cold water way to test the doneness of candy. Below there are directions for both.
Thread Stage - begins at 230 degrees F. - Makes a long thread when dropped in cold water.
Soft Ball - 234 degrees F. - Forms a soft ball that doesn't hold its shape. Cream candies, fudge, fondants are done at the soft ball stage.
Firm Ball - 246 degrees F. - This ball will only flatten with pressure. Divinity and Caramels.
Hard Ball - 250 degrees F. - This ball will hold its shape when pressed. Taffy.
Soft Crack - 270 degrees F. - Separates into bendable threads. Toffee and Butterscotch.
Hard Crack - 300 degrees F. - Becomes brittle. Peanut Brittle.
Caramelize - 310 degrees F. - Sugar turns dark.
HTHs!
it's the other way around... a tsp of the syrup in a cup of ice water. Then follow pp's About.com list for what to look for in the cooled blob.
And yes, I teach at a culinary school and we still get guffaws about cooking "to crack stage".
I remember now that this is how my mom does it (dropping a tsp in cold water), but she's more experienced than I!
LOL...in this case, I'd have to liken myself to toffee, and my husband to peanut brittle.
