I gave my eldest son a tutorial (at his request) on toffee making. We did a batch in San Diego...
...at my fil's house.
It was not easy, because he has an electric cook top, and I'm used to gas flame.
I'm happy to say we were successful.
I made a total of 7 batches this year between Phoenix and San Diego, and none of it seized. I think I've gotten the process down pat now, thankfully. There's nothing more disappointing than going through a process that "involved" and ending up with a bunch of seized, grainy, semi-stiff butter and sugar. (Not to mention the cost of 1/2 pound of butter and sugar.)
Maybe some day I'll do a YouTube video. REAL candy-makers will probably tear me to pieces, but, hey, my process works for me!
