Kitchen alchemy

I don't know what it is about some recipes. You stir a few perfectly straightforward ingredients together, slap the mixture in a pan, and bake it. You let it cool, cut it, and serve it to a random gathering of people. Women swoon. Men ask to marry you. Hell, women ask to marry you. Children smear it all over their faces. In very short order, you are left with nothing but an empty container and a circle of smiling people with chocolate in their teeth.

I've watched it happen with this one over and over again. My mother has been making these my whole life, and I've watched relatives gobble them up, friends embarrass themselves, and brothers-in-law swear they've only had two (not five) when they go for the last one. And it's not just a Boston thing: I swear there are still people in England who know me only as So-and-so's friend who brought those…things…to that party that time.

This weekend I was invited to a barbeque, and asked to bring a dessert, so I tried these out on an Australian contingent: partly because the recipe was about all I had the mental energy for, and partly out of curiosity to see if I would get the same reaction.

The result: the only reason I had those two available for picture-taking is because they wouldn't fit in the container that I took to the party.

Please try these and tell me if you get the same reaction. I'm always looking to broaden my data sample on just what it is about this recipe that drives people crazy.

Congo bars
Adapted from Rosie's Bakery All-Butter Fresh Cream Sugar-Packed No-Holds-Barred Baking Book
My mother's recipe uses Crisco, but I've found English and Australian vegetable shortening to be quite different in texture and density, and producing different results when used in baking. So I hunted down this version that uses butter, and now I like it even better, if that's possible. (Oh, and no, I don't know why they're called congo bars either. If you do, please enlighten us.)

1 1/3/280 g cups plain/all-purpose flour
1 ½ tsp baking soda
½ tsp salt
9 Tbsp (1 stick + 1 Tbsp)/125 g butter, softened
1 ¾ cups/350 g light brown sugar*
1 ¼ tsp vanilla extract
2 large eggs at room temperature
1 cup/120 g semisweet chocolate chips
½ cup/60 g coconut

Preheat oven to 350F/180C. Grease an 8 in x 8 in/20 cm x 20 cm square baking pan.

Blend dry ingredients and set aside.

With an electric mixer on medium, cream butter, sugar, and vanilla until light and fluffy (about 2 minutes). Scrape down the sides of the bowl as necessary.

Add eggs, mix on high briefly (about 3-5 seconds), then on medium until well blended (about 7-10 seconds).

Add dry ingredients and mix on low until combined (8-10 seconds).

Fold in chocolate and coconut until thoroughly mixed through. Spread evenly in baking pan.

Bake for about 30 minutes, rotating pan halfway through, or until it has a rich golden crust and the center has sunk. Cool in pan for at least 30 minutes before slicing.

Makes 25 1-inch bars.

* I use whatever kind of brown sugar I have on hand. It changes the texture somewhat, but they're pretty much always good.
