It’s hard to find candy that doesn’t include corn syrup as an ingredient. I make the things I miss (and sometimes the things that my kids miss); one of those is peanut brittle because it always reminds me of my grandfather. If you’re allergic to peanuts, another nut could probably be substituted; I, however, have not tried it.
1 1/2 c. roasted, salted peanuts (look at ingredients carefully to make sure that they’re safe for you)
1/4 tsp. ground cinnamon
3 c. safe sugar (I use palm or beet sugar)
1 1/2 c. water
Place sugar and water in a heavy saucepan. Cook over medium-high to high heat until it comes to a boil. Reduce heat to medium, and boil to hard crack stage (300F on candy thermometer). Remove from heat and quickly stir in nuts and cinnamon. Spread onto greased parchment paper. Let cool, then break into pieces.
