Best way to flavor toffee
I'm experimenting with toffee recipes to make for christmas gifts. I have a great recipe for regular english toffee but I'd like to make some orange pecan toffee. I've seen people put candied orange peel on top of regular toffee, but I'd really like to flavor the candy itself. I was thinking about adding either a little bit of orange oil or substituting orange juice (maybe concentrate?) for the water. Any ideas or suggestions for other flavors I could try? If you think orange oil is a good idea, how much should I use to flavor two pounds of toffee?
