Drowning as I am in cakes and cookies and sweet breads, I have absolutely no business - none! - making brownies on my day off. But I couldn't help it! I'm sorry! It's just that I was looking through a book that a British publisher sent to me last year (written by a German baker living in London) when something on page 141 called Boston Brownies caught my eye.

Now as you know, I have spent many a year in Boston, both as a child and a college student, and I have never, in all that time, heard of a Boston brownie. (Have you?) I had to read a little closer. My interest was piqued! Turns out that Gerhard Jenne, inspired by the fresh cranberries he discovered on a trip to Massachusetts, decided to pop a bunch of them in a brownie batter. The result - sort of like an American take on the Black Forest Cake of his youth - was so good he put the recipe in the book.

I was intrigued. I was also a little skeptical. I mean, fresh cranberries? With chocolate? (Also, er,  Anglo-German brownies?) The recipe looked really easy, though, and it was Sunday and I happened to have frozen cranberries in the freezer, so I decided to go for it and I am here to tell you now that these brownies are amazing.

AMAZING.

You all. The brownies themselves, made with a mix of bittersweet chocolate and cocoa, are incredibly fudgy and dark with a gorgeous crackling crust. So the recipe would be a keeper for that alone. But the addition of the cranberries is, in fact, totally inspired - the sour, fruity pop against all that rich, dark chocolate is really delicious. We took the brownies to tea at our friends' house, where we each ate two pieces (Hugo included!) and then the men each ate a third while I tried to distract Hugo from demanding more by throwing myself on the floor and pretending to be a car. (It worked!)

In conclusion:

A.The world does need another brownie recipe.

B. Fresh cranberries in brownies are brilliant.

C. Anglo-German bakers have got the brownie thing figured out.

Oh, and furthermore! Do not repeat my dunderheaded mistake of always leaving the pan of brownies wherever I bring them. Make sure to keep a few for yourself the next day or you will regret it. Speaking from experience. Ahem.

Gerhard Jenne's Bittersweet Brownies with Cranberries
Adapted from Deservedly Legendary Baking
Makes 16
Note: The original recipe calls for 200 grams of chocolate and only 1 tablespoon of cocoa, but I didn't have enough chocolate in the house that day, so I made do with what I had and upped the amount of cocoa. I loved the result, so that's what I've listed below.

3 eggs
1 1/3 cups (275 grams) sugar
6 1/4 ounces (175 grams) butter
6 1/4 ounces (175 grams) dark chocolate (54 – 60% cocoa solids), chopped into small pieces
1 1/3 cup flour plus 1 tablespoon (175 grams) all-purpose flour
3 tablespoons cocoa powder
1/4 teaspoon salt
6 1/4 ounces (175 grams) fresh cranberries

1. Heat the oven to 350 F (180 C). Line an 8 x 8-inch pan with parchment paper.

2. Break the eggs into a mixing bowl, then whisk in the sugar until frothy. Set aside.

3. Put the butter in a pan and melt over medium heat until it has completely melted and small bubbles are just beginning to rise to the surface. Turn off the heat, add the chocolate, and stir until melted.

4. Whisk the eggs and sugar again until pale and frothy, then whisk in the chocolate mixture until well combined. Sift in the flour and cocoa powder and stir gently with a spatula until there are no white streaks remaining. Add the salt. Fold in the cranberries. (If you're using frozen, this will cause the batter to seize up slightly, so work quickly.)

5. Scrape the mixture into the prepared pan and even the top. Bake for about 25 minutes, then take the pan from the oven and place on a cooling rack to cool completely. Cut into squares and serve.
