One thing I love about living in a big city is having access to authentic ethnic food products. I love perusing the aisles at grocery stores like Fiesta just to see what fun ingredients I can find and use.

On that note, one of my family’s favorite traditions is having Mexican food for our Christmas gathering. There are about 50 of us and all the women bring different dishes to share. After the traditional turkey and dressing Thanksgiving meal, it’s fun to having something different. Another tradition is that one of my aunts makes her homemade peanut brittle recipe, and passes out bags to everyone. It’s my favorite gift each year- it’s just so good!

The other day when I was at Fiesta, I grabbed a few cans of La Morena Jalapenos and a 6-pack of Coca Cola bottles.  I wanted to try my hand at making peanut brittle myself, but wanted to add a little twist to it- jalapenos. Now before you think I’m crazy, think about how good a sweet and spicy combo is. It’s one of my favorites!

I used the Coca Cola in lieu of some of the corn syrup and sugar, and it gave the peanut brittle recipe a nice rich dark color. The jalapenos gave it a nice bit of spice without being over-the-top hot.

Let’s make this yumminess shall we? I based it off the peanut brittle recipe from Betty Crocker, but made several alterations.

baking soda peanut brittle

First, mix 1.5 tsp baking soda, 1 tsp water, and 1.5 tsp vanilla in a small bowl and set aside.

Coca Cola

Next, add 1 c. sugar, 3/4 c. Coca Cola, 3/4 c. light corn syrup, and 1 cup water to a medium-sized heavy sauce pan. Cook over medium until candy thermometer reaches 240 degrees, or the soft ball stage.

Next, add in 12 oz raw, unsalted peanuts + 3 Tbs. salted butter. Turn heat to medium high and heat until thermometer reaches 300 degrees, or the hard crack stage. Stir constantly during this time so the mixture doesn’t burn. When it reaches 300, turn off the heat. Add your baking soda mixture, plus 6-8 La Morena jalapeno pepper halves, finely chopped and patted dry. I love the authentic Mexican flair they add to this dish!

Quickly spread onto a greased cookie sheet with sides. Allow to harden for at least one hour. Enjoy with an ice-cold Coca Cola!
