OK if your brave enough to try it here is my toffee recipe. Make sure to hold on to your pan tight when pouring it out:)
1 cup of butter
1 cup of Nucoa margarine (it doesn't burn)
2 cup sugar
2 Tbs water (to help the butter and sugar blend better)
3/4 tsp vanilla
Start to melt the butter and water over medium heat in a bigger saucepan (it will rise some while boiling). Once it starts melting, add your sugar. You will have to constantly stir the mixture while it's cooking until it's done so it doesn't burn on the bottom of the pan. It'll take about 20 minutes or so to cook.
When it starts cooking it'll look like this...
I don't have a candy thermometer so I'll tell you how I tell when it's done. The mixture will start boiling and for a long time it'll look the same, then all the sudden it will start looking more brown (about the color of the toffee that was on my floor). Keep stirring it and after a couple of minutes or so start checking it to see if it's done.
My friend told me about this and it really works. Get a cup of cold water and drop a little bit of the toffee into the water. Wait a couple of seconds and pick it up. If the toffee is soft after being in the water it's still needs to cook longer. If the toffee is brittle and breaks apart when it's in the water it's done.
Remove it from the heat and then add the vanilla, stirring constantly. Immediately pour the toffee onto a cookie sheet. (Hold on tight:) Once it's poured on the sheet sprinkle chocolate chips over the top and spread them around with a spatula.
You can also sprinkle sliced almonds on the top if you would like, my family is fine without them.
I put the pan into the fridge and it cools faster. After it's cool and hard you can just break it up into peices. I also store mine in a tightly covered container in the fridge.
Good luck. Let me know if you try it and how it works for you.
